Significant Accounting Policies [Text Block]	1 Summary of Significant Accounting Policies

	The Company The accompanying consolidated financial statements include the accounts of Giga-tronics Incorporated (“Giga-tronics”) and its wholly-owned subsidiary, Microsource Incorporated (“Microsource”), collectively the “Company”. The Company’s corporate office and manufacturing facilities are located in San Ramon, California. Giga-tronics and its subsidiary company design, manufacture and market a broad line of test and measurement equipment used in the development, test, and maintenance of wireless communications products and systems, flight navigational equipment, electronic defense systems, and automatic testing systems. The Company also manufactures and markets a line of test, measurement, and handling equipment used in the manufacturing of semiconductor devices. The Company’s products are sold worldwide to customers in the test and measurement and semiconductor industries. The Company currently has no foreign-based operations or material amounts of identifiable assets in foreign countries. Its gross margins on foreign and domestic sales are similar, and all non-U.S. sales are transacted in U.S. dollars.

	Principles of Consolidation The consolidated financial statements include the accounts of Giga-tronics and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.

	Basis of Presentation The consolidated financial statements are presented on the assumption that the company will continue to operate as a going concern. Discussion of recent events that Management believes support this presentation are as follows:

	In fiscal 2012 the Company began to invest heavily in the development of a new Giga-tronics Division product platform, the Advanced Signal Generation System. Delays in completing the Advanced Signal Generation System have contributed significantly to the losses of the Company. In fiscal 2015 the Company’s net loss was $1.7 million, which included a non-cash expense of $1.2 million related to the issuance of new warrants to Alara Capital and $152,000 of non-cash accretion of loan and warrant debt discounts. Also in fiscal 2015 the Company had operating income of $14,000, compared to an operating loss of $4.5 million in fiscal 2014.

	In the fourth quarter of fiscal 2015 the Company received $1.5 million of net proceeds associated with Alara Capital exercising 1,002,818 of existing warrants (see Note 17, Exercise of Series C and Series D Warrants). Also in the fourth quarter of fiscal 2015 two customers formally accepted initial units of the Company’s new Advanced Signal Generation System. With initial customer acceptance of Advanced Signal Generation System units, similar units of the new platform are in production for potential future sales to customers. The Company could experience longer than anticipated sales cycles or delays in production and shipping volume quantities of the Advanced Signal Generation System, however, the Company believes the Advanced Signal Generation System will significantly contribute to the Company’s long term success. On June 1, 2015 the Company entered into a two year $2.5 million Revolving Accounts Receivable Line of Credit agreement with Bridge Bank. The Bridge Bank credit facility replaced the line of credit with SVB, which expired April 15, 2015. The $2.5 million credit facility includes $500,000 on a non-formula basis in addition to the Borrowing Base. (see Note 18, Subsequent Events).

	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

	Fiscal Year The Company’s financial reporting year consists of either a 52 week or 53 week period ending on the last Saturday of the month of March. Fiscal year 2015, ended on March 28, 2015 resulting in a 52 week year. Fiscal year 2014, ended on March 29, 2014 also resulting in a 52 week year. All references to years in the consolidated financial statements relate to fiscal years rather than calendar years.

	Reclassifications Certain reclassifications, none of which affected the prior year’s net loss or shareholders’ equity, have been made to prior year balances in order to conform to the current year presentation.

	Revenue Recognition and Deferred Revenue The Company records revenue when there is persuasive evidence of an arrangement, delivery has occurred, the price is fixed and determinable, and collectability is reasonably assured. This occurs when products are shipped or the customer accepts title transfer. If the arrangement involves acceptance terms, the Company defers revenue until product acceptance is received. On certain large development contracts, revenue is recognized upon achievement of substantive milestones. Determining whether a milestone is substantive is a matter of judgment and that assessment is performed only at the inception of the arrangement. The consideration earned from the achievement of a milestone must meet all of the following for the milestone to be considered substantive:

	a. It is commensurate with either of the following:

	1. The Company’s performance to achieve the milestone.

	2. The enhancement of the value of the delivered item or items as a result of a specific outcome resulting from the Company's performance to achieve the milestone.

	b. It relates solely to past performance.

	c. It is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement.

	Milestones for revenue recognition are agreed upon with the customer prior to the start of the contract and some milestones are based on product shipping while others are based on design review. In fiscal 2015 the Company’s Microsource business unit received a $6.5 million order from a major aerospace company for non-recurring engineering services to develop a variant of its high performance fast tuning YIG filters for an aircraft platform and to deliver a limited number of flight-qualified prototype hardware units (the “NRE Order”) which is being accounted for on a milestone basis. The Company considered factors such as estimated completion dates and product acceptance of the order prior to accounting for the NRE Order as milestone revenue. During the fiscal years ended March 28, 2015 and March 29, 2014, revenue recognized on a milestone basis were $4.7 million and $486,000, respectively.

	On certain contracts with several of the Company’s significant customers the Company receives payments in advance of manufacturing. Advanced payments are recorded as deferred revenue until the revenue recognition criteria described above has been met.

	Accounts receivable are stated at their net realizable value. The Company has estimated an allowance for uncollectable accounts based on analysis of specifically identified accounts, outstanding receivables, consideration of the age of those receivables, the Company’s historical collection experience, and adjustments for other factors management believes are necessary based on perceived credit risk.

	The activity in the reserve account for doubtful accounts is as follows for the years ending March 28, 2015 and March 29, 2014:

	(Dollars in thousands)		28-Mar-15		29-Mar-14
	Beginning balance		$	44	$	35
	Provisions (reversals of previous provisions) for doubtful accounts			1		22
	Write-off of doubtful accounts			—		(13	)
	Ending balance		$	45	$	44

	Accrued Warranty The Company’s warranty policy generally provides one to three years of coverage depending on the product. The Company records a liability for estimated warranty obligations at the date products are sold. The estimated cost of warranty coverage is based on the Company’s actual historical experience with its current products or similar products. For new products, the required reserve is based on historical experience of similar products until such time as sufficient historical data has been collected on the new product. Adjustments are made as new information becomes available.

	Inventories Inventories are stated at the lower of cost or fair value using full absorption and standard costing. Cost is determined on a first-in, first-out basis. Standard costing and overhead allocation rates are reviewed by management periodically, but not less than annually. Overhead rates are recorded to inventory based on capacity management expects for the period the inventory will be held. Reserves are recorded within cost of sales for impaired or obsolete inventory when the cost of inventory exceeds its estimated fair value. Management evaluates the need for inventory reserves based on its estimate of the amount realizable through projected sales including an evaluation of whether a product is reaching the end of its life cycle. When inventory is discarded it is written off against the inventory reserve, as inventory generally has already been fully reserved for at the time it is discarded.

	Research and Development Research and development expenditures, which include the cost of materials consumed in research and development activities, salaries, wages and other costs of personnel engaged in research and development, costs of services performed by others for research and development on the Company’s behalf and indirect costs are expensed as operating expenses when incurred. Research and development costs totaled approximately $3.2 million and $3.9 million for the years ended March 28, 2015 and March 29, 2014, respectively.

	Property and Equipment Property and equipment are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, which range from three to ten years for machinery and equipment and office fixtures. Leasehold improvements and assets acquired under capital leases are amortized using the straight-line method over the shorter of the estimated useful lives of the respective assets or the lease term.

	The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such review indicates that the carrying amount of an asset exceeds the sum of its expected future cash flows on an undiscounted basis, the asset’s carrying amount would be written down to fair value. Additionally, the Company reports long-lived assets to be disposed of at the lower of carrying amount or fair value less cost to sell. As of March 28, 2015 and March 29, 2014, management believes there has been no impairment of the Company’s long-lived assets.

	Derivatives The Company accounts for free standing derivatives and embedded derivatives required to be bifurcated and accounted for on a stand-alone basis at estimated fair value. Changes in fair value are reported in earnings as other income or loss.

	Deferred Rent Rent expense is recognized in an amount equal to the guaranteed base rent plus contractual future minimum rental increases amortized on the straight-line basis over the terms of the leases, including free rent periods.

	Income Taxes Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Future tax benefits are subject to a valuation allowance when management is unable to conclude that its deferred tax assets will more likely than not be realized. The ultimate realization of deferred tax assets is dependent upon generation of future taxable income during the periods in which those temporary differences become deductible. Management considers both positive and negative evidence and tax planning strategies in making this assessment.

	The Company considers all tax positions recognized in its financial statements for the likelihood of realization. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the positions taken or the amounts of the positions that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above, if any, would be reflected as unrecognized tax benefits, as applicable, in the accompanying consolidated balance sheets along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits as a component of the provision for income taxes in the consolidated statements of operations.

	Product Development Costs The Company incurs pre-production costs on certain long-term supply arrangements. The costs, which represent non-recurring engineering and tooling costs, are capitalized as other assets and amortized over their useful life when reimbursable by the customer. All other product development costs are charged to operations as incurred. Capitalized pre-production costs included in inventory were immaterial as of March 28, 2015 and March 29, 2014.

Software Development Costs Development costs included in the research and development of new products and enhancements to existing products are expensed as incurred, until technological feasibility in the form of a working model has been established. To date, completion of software development has been concurrent with the establishment of technological feasibility, and accordingly, no costs have been capitalized.

Share-based Compensation The Company has established the 2005 Equity Incentive Plan, which provides for the granting of options for up to 2,250,000 shares of Common Stock. In 2014, the term of the 2005 Equity Incentive Plan was extended to 2025. The Company records share-based compensation expense for the fair value of all stock options and restricted stock that are ultimately expected to vest as the requisite service is rendered.

The cash flows resulting from the tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) are classified as cash flows from financing in the statements of cash flows. These excess tax benefits were not significant for the Company for the fiscal years ended March 28, 2015 or March 29, 2014.

In calculating compensation related to stock option grants, the fair value of each stock option is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The computation of expected volatility used in the Black-Scholes-Merton option-pricing model is based on the historical volatility of Giga-tronics’ share price. The expected term is estimated based on a review of historical employee exercise behavior with respect to option grants. The risk free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. Expected dividend yield was not considered in the option pricing formula since the Company has not paid dividends and has no current plans to do so in the future.

The fair value of restricted stock awards is based on the fair value of the underlying shares at the date of the grant. Management makes estimates regarding pre-vesting forfeitures that will impact timing of compensation expense recognized for stock option and restricted stock awards.

Earnings or Loss Per Common Share Basic earnings or loss per common share is computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share incorporate the incremental shares issuable upon the assumed exercise of stock options and warrants using the treasury stock method. Anti-dilutive options are not included in the computation of diluted earnings per share. Non-vested shares of restricted stock have nonforfeitable dividend rights and are considered participating securities for the purpose of calculating basic and diluted earnings per share under the two-class method.

Comprehensive Income or Loss There are no items of comprehensive income or loss other than net income or loss.

Financial Instruments and Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist of cash, cash-equivalents and trade accounts receivable. The Company’s cash-equivalents consist of overnight deposits with federally insured financial institutions. Concentration of credit risk in trade accounts receivable results primarily from sales to major customers. The Company individually evaluates the creditworthiness of its customers and generally does not require collateral or other security. At March 28, 2015, and March 29, 2014, three customers combined accounted for 65% of consolidated gross accounts receivable.

Fair Value of Financial Instruments and Fair Value Measurements The Company’s financial instruments consist principally of cash and cash-equivalents, line of credit, term debt, warrant liability and warrant derivative liability. The fair value of a financial instrument is the amount at which the instrument could be exchanged in an orderly transaction between market participants to sell the asset or transfer the liability. The Company uses fair value measurements based on quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access as of the measurement date (Level 1), significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data (Level 2), or significant unobservable inputs reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability (Level 3), depending on the nature of the item being valued.

The carrying amounts of the Company’s cash and cash-equivalents and line of credit approximate their fair values at each balance sheet date due to the short-term maturity of these financial instruments. The fair values of term debt and warrant debt are based on the present value of expected future cash flows and assumptions about current interest rates and the creditworthiness of the Company (Level 3). At March 28, 2015 the carrying amounts of the Company’s term debt and warrant debt totaled $1.1 million and $82,000, respectively. At March 28, 2015 the estimated fair values of the Company’s term debt and warrant debt totaled $1.2 million and $112,000, respectively. At March 29, 2014, the carrying amounts of the Company’s term debt and warrant debt totaled $822,000 and $50,000, respectively, and the carrying amounts approximated fair value since the agreement was entered into near the balance sheet date. The fair value of the bifurcated conversion feature represented by the warrant derivative liability which is measured at fair value on a recurring basis is based on a Black Scholes option pricing model with assumptions for stock price, exercise price, volatility, expected term, risk free interest rate and dividend yield similar to those described previously for share-based compensation which were generally observable (Level 2). The Company had no assets or liabilities measured at fair value on a non-recurring basis, nor were there any transfers between Level 1 and Level 2 of the fair value hierarchy.

In April 2014, the Financial Accounting Standards Board (FASB) issued an accounting standard update that changes the criteria for reporting discontinued operations. Under the accounting standard update, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results when either it qualifies as held for sale, disposed of by sale, or disposed of other than by sale. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2016. The Company is currently evaluating the impact of this accounting standard update on its Consolidated Financial Statements.

In May 2014, the FASB amended the accounting standards by creating a new Topic 606 which is in response to a joint initiative of the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. generally accepted accounting principles and international financial reporting standards that would:

	1	Remove inconsistencies and weaknesses in revenue requirements.

	2	Provide a more robust framework for addressing revenue issues.

	3	Improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets.

	4	Provide more useful information to users of financial statements through improved disclosure requirements.

	5	Simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer.

For a public entity, the amendments in this Update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The Company is currently evaluating the impact this new accounting standard will have on its financial statements.

In June 2014, the FASB amended ASC 718, Share Based Compensation, to require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. For all entities, the amendments in this update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. The Company is currently evaluating the impact this accounting standard update may have on its financial statements.

In August 2014, the FASB issued ASU 2014-15 which provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. The ASU applies to all entities and is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the impact this accounting standard update may have on its financial statements.

In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs,” or ASU 2015-03. ASU 2015-03 simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct reduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this ASU. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The adoption of this ASU by the Company will change the presentation of debt issuance costs, which will be reported as a direct offset to the applicable debt on the balance sheet.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	7 Significant Customers and Industry Segment Information

	The Company has two reportable segments: Giga-tronics Division and Microsource. Giga-tronics Division produces a broad line of test and measurement equipment used in the development, test and maintenance of wireless communications products and systems, flight navigational equipment, electronic defense systems and automatic testing systems and designs, manufactures, and markets a line of switching devices that link together many specific purpose instruments that comprise automatic test systems. Microsource develops and manufactures a broad line of Yttrium, Iron and Garnet (YIG) tuned oscillators, filters and microwave synthesizers, which are used in a wide variety of microwave instruments or devices.

	The accounting policies for the segments are the same as those described in the "Summary of Significant Accounting Policies". The Company evaluates the performance of its segments and allocates resources to them based on earnings before income taxes. Segment net sales include sales to external customers. Inter-segment activities are eliminated in consolidation. Assets include accounts receivable, inventories, equipment, cash, deferred income taxes, prepaid expenses and other long-term assets. The Company accounts for inter-segment sales and transfers at terms that allow a reasonable profit to the seller. During the periods reported there were no significant inter-segment sales or transfers.

	The Company's reportable operating segments are strategic business units that offer different products and services. They are managed separately because each business utilizes different technology and requires different accounting systems. The Company’s chief operating decision maker is considered to be the Company’s Chief Executive Officer (“CEO”). The CEO reviews financial information presented on a consolidated basis accompanied by disaggregated information about revenues and pre-tax income or loss by operating segment.

	The following summarizes the difference between the income tax expense and the amount computed by applying the statutory federal income tax rate of 34% to income before income tax. The items comprising these differences consisted of the following for the fiscal years ended March 28, 2015 and March 29, 2014:

	Fiscal years ended (In thousands except percentages)	28-Mar-15						29-Mar-14
	Statutory federal income tax (benefit)	$	(553	)		34	%	$	(1,256	)	34	%

	Other		29			(1.8	)		2		(0.1	)
	Effective income tax	$	47			3	%	$	2		(0.1	)%

	The decrease in valuation allowance from March 29, 2014 to March 28, 2015 was $624,000.

	As of March 28, 2015, the Company had pre-tax federal net operating loss carryforwards of $35.9 million and state net operating loss carryforwards of $25.0 million available to reduce future taxable income. The federal and state net operating loss carryforwards begin to expire from fiscal 2023 through 2035 and from 2015 through 2035, respectively. Utilization of net operating loss carryforwards may be subject to annual limitations due to certain ownership change limitations as required by Internal Revenue Code Section 382. The federal income tax credits begin to expire from 2021 through 2035 and state income tax credit carryforwards are carried forward indefinitely.

	The Company has recorded a valuation allowance to reflect the estimated amount of deferred tax assets, which may not be realized. The ultimate realization of deferred tax assets is dependent upon generation of future taxable income during the periods in which those temporary differences become deductible. Management considers both positive and negative evidence and tax planning strategies in making this assessment.

	As of March 28, 2015, the Company recorded unrecognized tax benefits of $93,000 related to uncertain tax positions. The unrecognized tax benefit is netted against the noncurrent deferred tax asset on the Consolidated Balance Sheet. The Company has not recorded a liability for any penalties or interest related to the unrecognized tax benefits.

	The Company files U.S federal and California state income tax returns. The Company is generally no longer subject to tax examinations for years prior to the fiscal year 2012 for federal purposes and fiscal year 2011 for California purposes, except in certain limited circumstances. The Company does have a California Franchise Tax Board audit that is pending. The Company is working with the California Franchise Tax Board to resolve all audit issues and does not believe any material taxes or penalties are due. However, as a result of the ongoing examination, the Company eliminated certain income tax credit carryovers in fiscal 2014. The write-off of these income tax credit carryovers did not have a significant impact on total income tax expense as the majority had an uncertain tax position reserve with the balance having a full valuation allowance against the deferred tax asset.

	A reconciliation of the beginning and ending amount of the liability for uncertain tax positions, excluding potential interest and penalties, is as follows:

	(In thousands)	Fiscal Year 2015			Fiscal Year 2014
	Balance as of beginning of year	$	70		$	1,649
	Additions based on current year tax positions		23			—
	(Reductions) additions for prior year tax positions		—			(1,579	)
	Balance as of end of year	$	93		$	70

The total amount of interest and penalties related to unrecognized tax benefits at March 28, 2015 is not material. The amount of tax benefits that would impact the effective rate, if recognized, is not expected to be material. The Company does not anticipate any significant changes with respect to unrecognized tax benefits within next twelve (12) months.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	10 Share-based Compensation and Employee Benefit Plans

	Share-based Compensation The Company has established the 2000 Stock Option Plan and the 2005 Equity Incentive Plan, which provide for the granting of options and restricted stock for up to 2,250,000 shares of common stock at 100% of fair market value at the date of grant, with each grant requiring approval by the Board of Directors of the Company. Option grants under the 2000 Stock Option Plan are no longer available. Options granted generally vest in one or more installments in a four or five year period and must be exercised while the grantee is employed by the Company or within a certain period after termination of employment. Options granted to employees shall not have terms in excess of 10 years from the grant date. Holders of options may be granted stock appreciation rights (SAR), which entitle them to surrender outstanding options for a cash distribution under certain changes in ownership of the Company, as defined in the stock option plan. As of March 28, 2015, no SAR’s have been granted under the option plan. As of March 28, 2015, the total number of shares of common stock available for issuance is 397,425. All outstanding options have either a five year or a ten year life.

	The weighted average grant date fair value of stock options granted during the fiscal years ended March 28, 2015 and March 29, 2014 was $1.66 and $1.07, respectively, and was calculated using the following weighted-average assumptions:

	Fiscal years ended	28-Mar-15			29-Mar-14
	Dividend yield		—			—
	Expected volatility		92	%		86	%
	Risk-free interest rate		1.61	%		1.02	%
	Expected term (years)		8.34			7.91

	At March 28, 2015, expected to vest in the future		761,212		$	1.54			7.4	$	107

	As of March 28, 2015, there was $1.2 million of total unrecognized compensation cost related to non-vested options and restricted stock granted under the 2005 Plan and outside of the 2005 Plan. That cost is expected to be recognized over a weighted average period of 2.5 years and will be adjusted for subsequent changes in estimated forfeitures. There were 280,650 and 320,525 options vested during the fiscal years ended March 28, 2015 and March 29, 2014 respectively. The total fair value of options vested during the fiscal years ended March 28, 2015 and March 29, 2014 was $120,000 and $365,000, respectively. Cash received from the exercise of stock options during fiscal 2015 was $163,000. No cash was received from the exercise of stock options in fiscal 2014. Share based compensation cost recognized in operating results for the fiscal years ended March 28, 2015 and March 29, 2014 totaled $370,000 and $310,000, respectively.

	Included in the total options outstanding at March 28, 2015 are performance-based options for 100,000 shares granted, which were granted outside of the 2005 Plan. All of the options vest following the filing of the Company’s Form 10-K for fiscal 2015 given certain bookings goals that were achieved by the Company. Compensation cost recognized in fiscal 2015 related to these options were $29,000, and no compensation cost was recognized for these stock options during fiscal 2014 because management did not believe the performance criteria would be met.

	During the year ended March 29, 2014, the vesting for 40,000 options was accelerated in connection with a termination agreement with a former employee. This modification did not result in any incremental compensation expense, however $7,000 of stock-based compensation expense was accelerated and recognized during the year ended March 29, 2014.

	Restricted Stock

	The Company granted 432,000 shares of restricted stock during fiscal 2015 to certain members of the Board of Directors in lieu of services to be performed in fiscal 2015 and fiscal 2016. The weighted average grant date fair value was $2.11. In fiscal 2014, the Company granted 71,500 shares of restricted stock to certain members of the Board of Directors in lieu of cash compensation for services to be performed in fiscal 2014. The weighted average grant date fair value was $1.53. The Company also granted 30,000 shares of unrestricted stock during 2014 as part of a severance agreement with a former employee. The 30,000 shares did not have a restriction period because they vested immediately on the grant date, but are included in the roll forward schedule of restricted stock below because they were granted under the 2005 Plan. The Company granted 50,000 shares of restricted stock outside the 2005 Plan in fiscal 2013. The restricted stock awards are considered fixed awards as the number of shares and fair value at the grant date is amortized over the requisite service period net of estimated forfeitures. Compensation cost recognized for restricted stock awards for 2015 and 2014 totaled $457,000 and $184,000, respectively.

	A summary of the changes in non-vested restricted stock awards outstanding for the fiscal years ended March 28, 2015 and March 29, 2014 is presented below:

					Weighted
					Average Grant
		Shares			Date Fair Value
	Non-vested at March 30, 2013		50,000		$	1.18
	Granted		101,500			1.53

	Forfeited or cancelled		—			—
	Non-vested at March 28, 2015		482,000		$	2.02

	401(k) Plans The Company has established 401(k) plans which cover substantially all employees. Participants may make voluntary contributions to the plans for up to 100% of their defined compensation. The Company matches a percentage of the participant’s contributions in accordance with the plan. Participants vest ratably in Company contributions over a four-year period. Company contributions to the plans for fiscal 2015 and 2014 were approximately $39,000 and $44,000, respectively.

	On June 11, 2013 the Company entered into an amendment to the Second Amended Credit Facility (the “New Amended Credit Facility”) with Silicon Valley Bank (the “Bank”). The New Amended Credit Facility amended the Second Amended Credit Facility by expanding the definition of eligible accounts, increasing the maximum limit, and extending the maturity date. The New Amended Credit Facility, which expired on April 15, 2015 and was replaced on June 1, 2015 with a $2.5 million line of credit with Bridge Bank (see Note 18, Subsequent Events), was secured by all assets of the Company and provided for a borrowing capacity equal to 80% of eligible accounts receivable (70% of eligible foreign accounts receivable) on an aggregate basis, up to a maximum $3.0 million, provided the Company maintained borrowing base eligibility, that is, a minimum of $750,000 of cash in excess of its line of credit liability.

	The Second Amended Credit Facility and New Amended Credit Facility contained a collateral handling fee of one-tenth of one percent (0.10%) on outstanding financed receivables for each calendar month based upon a 360 day year. When the Company was borrowing base eligible, the collateral handling fee was not applicable. Interest accrued on the average outstanding borrowings at a floating per annum rate equal to the greater of the Prime Rate plus two percent (2.00%) or six percent (6.00%). When the Company was borrowing base eligible, any borrowings under the New Amended Credit Facility could be repaid and such repaid amounts re-borrowed until the maturity date. When the Company was not borrowing base eligible, advances were made on the New Amended Credit facility on individual accounts receivable and the Company was required to instruct its customers to remit payments to a lockbox at the Bank and when the Company was not borrowing base eligible, such payments are applied by the Bank to the line of credit to the extent monies were advanced to the Company based on such specific accounts receivable. As of March 28, 2015, the Company was borrowing base eligible however there were no borrowings at March 28, 2015.

	As of March 28, 2015, the maximum borrowing capacity under the Line of Credit was $1.8 million, of which the entire amount was available. The Bank may have terminated or suspended the Company’s right to advances under the line of credit if the Bank had determined there had been a material adverse change in the Company’s general affairs, financial forecasts or general ability to repay.

	On June 16, 2014 the Company amended the term loan agreement with PFG creating a $500,000 revolving line of credit on which the Company drew $500,000. (see Note 15, Term Loan , Revolving Line of Credit and Warrants).

15 Term Loan, Revolving Line of Credit and Warrants

On March 13, 2014 the Company entered into a three year, $2.0 million term loan agreement with PFG under which the Company received $1.0 million on March 14, 2014. Pursuant to the agreement, the Company had the ability to borrow an additional $1.0 million following the Company’s achievement of certain performance milestones which includes achieving $7.5 million in net sales during the first half of fiscal 2015 and two consecutive quarters of net income greater than zero during fiscal 2015.

On June 16, 2014, the Company amended its loan agreement with PFG (the “Amendment”). Under the terms of the Amendment, PFG made a revolving credit line available to Giga-tronics in the amount of $500,000, and the Company borrowed the entire amount on June 17, 2014. The revolving line has a thirty-three month term. The Amendment reduced the future amount potentially available for the Company to borrow under the PFG Loan agreement from $1.0 million to $500,000.

On June 3, 2015, the Company further amended its loan agreement with PFG (the “Second Amendment”). The Second Amendment cancelled the additional $500,000 that was available to the Company under the June 2014 Amendment (see Note 18, Subsequent Events).

Interest on the initial $1.0 million term loan is fixed at 9.75% and requires monthly interest only payments during the first six months of the agreement followed by monthly principal and interest payments over the remaining thirty months. The Company may prepay the loan at any time prior to maturity by paying all future scheduled principal and interest payments. As of March 28, 2015, the Company’s total outstanding debt associated with the initial PFG loan was $800,000.

Interest on the $500,000 revolving line with PFG is fixed, calculated on a daily basis at a rate of 12.50% per annum. The Company may prepay the loan at any time prior to the March 13, 2017 maturity date without a penalty. Beginning in October 2014, PFG had the right to convert the $500,000 revolving loan into a term loan and require principal payments to be amortized over the remaining loan term. On April 25, 2015, PFG exercised this right, and fully amortizing principal and interest payments are scheduled to begin in May 2015. As of March 28, 2015, the $500,000 revolving line was fully advanced.

The PFG Loan is secured by all of the assets of the Company under a lien that is junior to the SVB position described in Note 14, and limits borrowing under the SVB credit line limit to $3.0 million. The Company paid a loan fee of $30,000 upon the initial draw (“First Draw”) and $15,000 for the June 2014 Amendment. The loan fees paid are recorded as prepaid expenses and amortized to interest expense over the remaining term of the PFG amended loan agreement.

The future payments under the initial loan and all the Amendments, were as follows as of March 28, 2015.

The loan agreement contains financial covenants associated with the Company achieving minimum quarterly net sales and maintaining a minimum monthly shareholders’ equity. In the event of default by the Company, all or any part of the Company’s obligation to PFG could become immediately due. As of March 28, 2015, the Company was in compliance with all the financial covenants under the agreement.

The loan agreement also provided for the issuance of warrants convertible into 300,000 shares of the Company’s common stock, of which 180,000 were exercisable upon receipt of the initial $1.0 million from the First Draw, 80,000 became exercisable with the Amendment. The Second Amendment terminated the additional 40,000 warrants that would have become exercisable as part of cancelling the remaining $500,000 that was available under the Amendment. Each warrant issued under the loan agreement has a term of five years from the First Draw and an exercise price of $1.42 which was equal to the average NASDAQ closing price of the Company’s common stock for the ten trading days prior to the First Draw.

If the warrants are not exercised before expiration on March 13, 2019, the Company would be required to pay PFG $150,000 and $67,000 as settlement for warrants associated with the First Draw and the Amendment, respectively. The warrants could be settled for cash at an earlier date in the event of any acquisition or other change in control of the Company, future public issuance of Company securities or liquidation (or substantially similar event) of the Company. The Company currently has no plans for any of the aforementioned events, and as a result, the cash payment date is estimated to be the expiration date unless warrants are exercised before then. Due to the fixed payment amount on the expiration date, the warrant structure is in substance a debt arrangement (the “Warrant Debt”) with a zero interest rate, a fixed maturity date and a feature that makes the debt convertible to common stock. The conversion feature is an embedded derivative and due to the downward adjustment feature based on performance criteria is not considered indexed solely to the Company’s stock. Thus, for accounting purposes, the conversion feature is bifurcated and accounted for separately from the host debt instrument as a derivative liability measured at fair value which resulted in an initial carrying value of $128,000 for the derivative liability associated with the warrants issued in connection with the First Draw and an initial carrying value of $123,000 for the derivative liability associated with the warrants issued in connection with the Amendment.

As of March 28, 2015, the estimated fair values of the derivative liabilities associated with the warrants issued in connection with the First Draw and Amendment were $174,000 and $78,000, respectively, for a combined value of $252,000. As of March 29, 2014, the estimated fair value of the derivative liability associated with the warrant issued in connection with the First Draw was $128,000. There was no derivative liability associated with the Amendment warrant at March 29, 2014. There was no change in the fair value of the derivative liabilities between fiscal 2015 and fiscal 2014 therefore there was no gains or losses on adjustment of derivative liability to fair value.

The proceeds from the initial $1.0 million draw were allocated between the PFG Debt and the Warrant Debt (inclusive of its conversion feature) based on their relative fair values on the date of issuance which resulted in initial carrying values of $822,000 and $178,000, respectively. The conversion feature was bifurcated from the Warrant Debt and recorded at fair value resulting in a remaining carrying value of $50,000 associated with the Warrant Debt. The resulting discounts of $178,000 on the PFG Debt and $100,000 on the Warrant Debt will be accreted to interest expense under the effective interest method over the three-year term of the PFG Debt and the five-year term of the Warrant Debt.

The proceeds from the $500,000 credit line issued in connection with the Amendment were allocated between the PFG Loan and the Warrant Debt (inclusive of its conversion feature) based on their relative fair values on the date of issuance which resulted in initial carrying values of $365,000 and $135,000, respectively. The conversion feature was bifurcated from the Warrant Debt and recorded at its $123,000 estimated fair value resulting in a remaining carrying value of $12,000 associated with the Warrant Debt. The resulting discounts of $135,000 on the PFG Loan and $55,000 on the Warrant Debt is being accreted to interest expense under the effective interest method over the thirty-three month remaining term of the PFG Loan and the fifty-seven month remaining term of the Warrant Debt. For fiscal 2015, the Company recorded accretion of discount expense associated with the warrants issued with the PFG Loan of $152,000, there was no accretion of discount expense recorded in fiscal 2014 as the loan was funded in late fiscal 2014.

	On November 10, 2011, the Company received $2,199,000 in cash proceeds from Alara Capital AVI II, LLC, a Delaware limited liability company (the “Investor”), an investment vehicle sponsored by Active Value Investors, LLC, under a Securities Purchase Agreement entered into on October 31, 2011. Under the terms of the Securities Purchase Agreement, the Company issued 9,997 shares of its Series B Convertible Voting Perpetual Preferred Stock (“Series B Preferred Stock”) to the Investor at a price of $220 per share. The Company has recorded $2.0 million as Series B Preferred Stock on the consolidated balance sheet which is net of stock offering costs of approximately $202,000 and represents the value attributable to both the convertible preferred stock and warrants issued to the Investor. After considering the value of the warrants, the effective conversion price of the preferred stock was greater than the common stock price on date of issue and therefore no beneficial conversion feature was present.

	On February 19, 2013, the Company entered into a Securities Purchase Agreement pursuant to which it agreed to sell 3,424.65 shares of its Series C Convertible Voting Perpetual Preferred Stock (“Series C Preferred Stock”) to the Investor, for aggregate consideration of $500,000, which is approximately $146.00 per share. The Company has recorded $457,000 as Series C Preferred Stock on the consolidated balance sheet, which is net of stock offering costs of approximately $43,000. After considering the reduction in the value of the warrant, the effective conversion price of the preferred stock was greater than the common stock price on the date of issue and therefore no beneficial conversion feature was present.

	On July 8, 2013 the Company received $817,000 in net cash proceeds from the Investor under a Securities Purchase Agreement. The Company sold to the Investor 5,111.86 shares of its Series D Convertible Voting Perpetual Preferred Stock (Series D Preferred Stock) and a warrant to purchase up to 511,186 additional shares of common stock at the price of $1.43 per share. The allocation of the $858,000 in gross proceeds from issuance of Series D Preferred Stock based on the relative fair values resulted in an allocation of $498,000 (which was recorded net of $41,000 of issuance costs) to Series D Preferred Stock and $360,000 to Common Stock. In addition, because the effective conversion rate based on the $498,000 allocated to Series D Preferred Stock was $0.97 per common share which was less than the Company’s stock price on the date of issuance, a beneficial conversion feature was present at the issuance date. The beneficial conversion feature totaled $238,000 and was recorded as a reduction of common stock and an increase to accumulated deficit.

	Each share of Series B, Series C and Series D Preferred Stock is convertible into one hundred shares of the Company’s common stock. The investor also held warrants to purchase 1,017,405 shares at an exercise price of $1.43 per share, Warrants were exercised in part in February 2015 as discussed in Note 17, Exercise of Series C and Series D Warrants.

	On February 16, 2015, the Company entered into a Securities Purchase Agreement and Warrant Agreement with Alara Capital AVI II, LLC (“Alara Capital”), an investment vehicle sponsored by AVI Partners, LLC (“AVI” ) (with both entities collectively referred to herein as “Alara”), in which the Company received total gross cash proceeds of approximately $1.5 million. Funds were received from Alara in separate closings dated February 16, 2015 and February 23, 2015 in which Alara exercised a total of 1,002,818 of its existing Series C and Series D warrants to purchase common shares, all of which had an exercise price of $1.43 per share for total cash proceeds of $1,434,000, which was recorded net of $42,000 of stock issuance costs. As part of the consideration for this exercise, the Company sold to Alara two new warrants to purchase an additional 898,634 and 194,437 common shares at an exercise price of $1.78 and $1.76 per share, respectively, for a total purchase price of $137,000 or $0.125 per share, The new warrants have a term of five years and may be paid in cash or through a cashless net share settlement. The Company and Alara amended the remaining 14,587 warrants as part of the February closings. On May 14, 2015, Alara exercised the remaining 14,587 warrants by acquiring 7,216 of shares of the Company’s common stock through a cashless net share settlement. The Company recorded the issuance of the new Warrants using their estimated fair value on the date of issuance. The Company estimated the fair value of the new Warrants using the Black-Scholes option valuation model with the following assumptions: expected term of 5 years, a risk-free interest rate of 1.54%, expected volatility of 90% and 0% expected dividend yield. The resulting $1.2 million from the issuance of the new Warrants was recorded as a charge to other expense in the current period.

	On June1, 2015 the Company entered into a $2.5 million Revolving Accounts Receivable Line of Credit agreement with Bridge Bank. The credit facility agreement replaced the line of credit with SVB which expired April 15, 2015. The agreement provides for a borrowing capacity of $2.5 million with the following sub-limits:

		●	$500,000 on a Non-Formula basis in addition to the Borrowing Base

		●	$100,000 under the Borrowing Base for International Services

		●	$100,000 under the Borrowing Base for Cash Management Services

	The loan is secured by all assets of the Company including intellectual property and general intangibles and provides for a borrowing capacity equal to 80% of eligible accounts receivable. The loan matures on May 6, 2017 and bears an interest rate 1.5% over the prime rate of interest (which was 3.25% at the date of closing resulting in an interest rate of 4.75%). Interest is payable monthly with principal due upon maturity. The Company paid a commitment fee of $12,500, and an additional $12,500 is due on the first anniversary of the loan closing. The loan agreement contains financial and non-financial covenants that are customary for this type of lending and includes a covenant to maintain an asset coverage ratio of at least 135% (defined as unrestricted cash and cash equivalents maintained with Bridge Bank N.A., plus eligible accounts receivable aged less than 90 days from the invoice date, divided by the total amount of outstanding principals of all obligations under the loan agreement). The amounts due under the facility could become immediately due in the event of default or in the event of a material adverse change in the Company’s business condition (financial or otherwise), operations, properties or prospects, or ability to repay the credit based on the judgment of lender.

	On June 3, 2015, concurrent with signing the $2.5 million Revolving Receivable Line of Credit with Bridge Bank, the Company amended its term loan agreement with PFG where PFG agreed to replace SVB with Bridge Bank as the holder of the first lien on the Company’s assets. The amended agreement also cancelled the additional $500,000 that was available to the Company under the June 2014 PFG Amendment. The Company agreed to pay PFG $150,000 principal payment towards the $500,000 outstanding revolving line of credit upon signing the amendment. The Company also agreed to pay PFG an additional $10,000 per month in principal payments until both loans are paid off, initially, the $10,000 will go against the $500,000 revolving line of credit, then against the term loan.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The consolidated financial statements are presented on the assumption that the company will continue to operate as a going concern. Discussion of recent events that Management believes support this presentation are as follows:

	In fiscal 2012 the Company began to invest heavily in the development of a new Giga-tronics Division product platform, the Advanced Signal Generation System. Delays in completing the Advanced Signal Generation System have contributed significantly to the losses of the Company. In fiscal 2015 the Company’s net loss was $1.7 million, which included a non-cash expense of $1.2 million related to the issuance of new warrants to Alara Capital and $152,000 of non-cash accretion of loan and warrant debt discounts. Also in fiscal 2015 the Company had operating income of $14,000, compared to an operating loss of $4.5 million in fiscal 2014.

	In the fourth quarter of fiscal 2015 the Company received $1.5 million of net proceeds associated with Alara Capital exercising 1,002,818 of existing warrants (see Note 17, Exercise of Series C and Series D Warrants). Also in the fourth quarter of fiscal 2015 two customers formally accepted initial units of the Company’s new Advanced Signal Generation System. With initial customer acceptance of Advanced Signal Generation System units, similar units of the new platform are in production for potential future sales to customers. The Company could experience longer than anticipated sales cycles or delays in production and shipping volume quantities of the Advanced Signal Generation System, however, the Company believes the Advanced Signal Generation System will significantly contribute to the Company’s long term success. On June 1, 2015 the Company entered into a two year $2.5 million Revolving Accounts Receivable Line of Credit agreement with Bridge Bank. The Bridge Bank credit facility replaced the line of credit with SVB, which expired April 15, 2015. The $2.5 million credit facility includes $500,000 on a non-formula basis in addition to the Borrowing Base. (see Note 18, Subsequent Events).
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements include the accounts of Giga-tronics and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fiscal Period, Policy [Policy Text Block]	Fiscal Year The Company’s financial reporting year consists of either a 52 week or 53 week period ending on the last Saturday of the month of March. Fiscal year 2015, ended on March 28, 2015 resulting in a 52 week year. Fiscal year 2014, ended on March 29, 2014 also resulting in a 52 week year. All references to years in the consolidated financial statements relate to fiscal years rather than calendar years.
Reclassification, Policy [Policy Text Block]	Reclassifications Certain reclassifications, none of which affected the prior year’s net loss or shareholders’ equity, have been made to prior year balances in order to conform to the current year presentation.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition and Deferred Revenue The Company records revenue when there is persuasive evidence of an arrangement, delivery has occurred, the price is fixed and determinable, and collectability is reasonably assured. This occurs when products are shipped or the customer accepts title transfer. If the arrangement involves acceptance terms, the Company defers revenue until product acceptance is received. On certain large development contracts, revenue is recognized upon achievement of substantive milestones. Determining whether a milestone is substantive is a matter of judgment and that assessment is performed only at the inception of the arrangement. The consideration earned from the achievement of a milestone must meet all of the following for the milestone to be considered substantive:

	a. It is commensurate with either of the following:

	1. The Company’s performance to achieve the milestone.

	2. The enhancement of the value of the delivered item or items as a result of a specific outcome resulting from the Company's performance to achieve the milestone.

	b. It relates solely to past performance.

	c. It is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) within the arrangement.

	Milestones for revenue recognition are agreed upon with the customer prior to the start of the contract and some milestones are based on product shipping while others are based on design review. In fiscal 2015 the Company’s Microsource business unit received a $6.5 million order from a major aerospace company for non-recurring engineering services to develop a variant of its high performance fast tuning YIG filters for an aircraft platform and to deliver a limited number of flight-qualified prototype hardware units (the “NRE Order”) which is being accounted for on a milestone basis. The Company considered factors such as estimated completion dates and product acceptance of the order prior to accounting for the NRE Order as milestone revenue. During the fiscal years ended March 28, 2015 and March 29, 2014, revenue recognized on a milestone basis were $4.7 million and $486,000, respectively.

	On certain contracts with several of the Company’s significant customers the Company receives payments in advance of manufacturing. Advanced payments are recorded as deferred revenue until the revenue recognition criteria described above has been met.

	Accounts receivable are stated at their net realizable value. The Company has estimated an allowance for uncollectable accounts based on analysis of specifically identified accounts, outstanding receivables, consideration of the age of those receivables, the Company’s historical collection experience, and adjustments for other factors management believes are necessary based on perceived credit risk.

	The activity in the reserve account for doubtful accounts is as follows for the years ending March 28, 2015 and March 29, 2014:

	(Dollars in thousands)		28-Mar-15		29-Mar-14

	Provisions (reversals of previous provisions) for doubtful accounts			1		22
	Write-off of doubtful accounts			—		(13	)
	Ending balance		$	45	$	44

	Accrued Warranty The Company’s warranty policy generally provides one to three years of coverage depending on the product. The Company records a liability for estimated warranty obligations at the date products are sold. The estimated cost of warranty coverage is based on the Company’s actual historical experience with its current products or similar products. For new products, the required reserve is based on historical experience of similar products until such time as sufficient historical data has been collected on the new product. Adjustments are made as new information becomes available.

	Inventories Inventories are stated at the lower of cost or fair value using full absorption and standard costing. Cost is determined on a first-in, first-out basis. Standard costing and overhead allocation rates are reviewed by management periodically, but not less than annually. Overhead rates are recorded to inventory based on capacity management expects for the period the inventory will be held. Reserves are recorded within cost of sales for impaired or obsolete inventory when the cost of inventory exceeds its estimated fair value. Management evaluates the need for inventory reserves based on its estimate of the amount realizable through projected sales including an evaluation of whether a product is reaching the end of its life cycle. When inventory is discarded it is written off against the inventory reserve, as inventory generally has already been fully reserved for at the time it is discarded.

	Research and Development Research and development expenditures, which include the cost of materials consumed in research and development activities, salaries, wages and other costs of personnel engaged in research and development, costs of services performed by others for research and development on the Company’s behalf and indirect costs are expensed as operating expenses when incurred. Research and development costs totaled approximately $3.2 million and $3.9 million for the years ended March 28, 2015 and March 29, 2014, respectively.

	Property and Equipment Property and equipment are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, which range from three to ten years for machinery and equipment and office fixtures. Leasehold improvements and assets acquired under capital leases are amortized using the straight-line method over the shorter of the estimated useful lives of the respective assets or the lease term.

	The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such review indicates that the carrying amount of an asset exceeds the sum of its expected future cash flows on an undiscounted basis, the asset’s carrying amount would be written down to fair value. Additionally, the Company reports long-lived assets to be disposed of at the lower of carrying amount or fair value less cost to sell. As of March 28, 2015 and March 29, 2014, management believes there has been no impairment of the Company’s long-lived assets.

	Derivatives The Company accounts for free standing derivatives and embedded derivatives required to be bifurcated and accounted for on a stand-alone basis at estimated fair value. Changes in fair value are reported in earnings as other income or loss.

	Deferred Rent Rent expense is recognized in an amount equal to the guaranteed base rent plus contractual future minimum rental increases amortized on the straight-line basis over the terms of the leases, including free rent periods.

	Income Taxes Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Future tax benefits are subject to a valuation allowance when management is unable to conclude that its deferred tax assets will more likely than not be realized. The ultimate realization of deferred tax assets is dependent upon generation of future taxable income during the periods in which those temporary differences become deductible. Management considers both positive and negative evidence and tax planning strategies in making this assessment.

	The Company considers all tax positions recognized in its financial statements for the likelihood of realization. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the positions taken or the amounts of the positions that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above, if any, would be reflected as unrecognized tax benefits, as applicable, in the accompanying consolidated balance sheets along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits as a component of the provision for income taxes in the consolidated statements of operations.

	Product Development Costs The Company incurs pre-production costs on certain long-term supply arrangements. The costs, which represent non-recurring engineering and tooling costs, are capitalized as other assets and amortized over their useful life when reimbursable by the customer. All other product development costs are charged to operations as incurred. Capitalized pre-production costs included in inventory were immaterial as of March 28, 2015 and March 29, 2014.

	Software Development Costs Development costs included in the research and development of new products and enhancements to existing products are expensed as incurred, until technological feasibility in the form of a working model has been established. To date, completion of software development has been concurrent with the establishment of technological feasibility, and accordingly, no costs have been capitalized.

	Share-based Compensation The Company has established the 2005 Equity Incentive Plan, which provides for the granting of options for up to 2,250,000 shares of Common Stock. In 2014, the term of the 2005 Equity Incentive Plan was extended to 2025. The Company records share-based compensation expense for the fair value of all stock options and restricted stock that are ultimately expected to vest as the requisite service is rendered.

	The cash flows resulting from the tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) are classified as cash flows from financing in the statements of cash flows. These excess tax benefits were not significant for the Company for the fiscal years ended March 28, 2015 or March 29, 2014.

	In calculating compensation related to stock option grants, the fair value of each stock option is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The computation of expected volatility used in the Black-Scholes-Merton option-pricing model is based on the historical volatility of Giga-tronics’ share price. The expected term is estimated based on a review of historical employee exercise behavior with respect to option grants. The risk free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. Expected dividend yield was not considered in the option pricing formula since the Company has not paid dividends and has no current plans to do so in the future.

	The fair value of restricted stock awards is based on the fair value of the underlying shares at the date of the grant. Management makes estimates regarding pre-vesting forfeitures that will impact timing of compensation expense recognized for stock option and restricted stock awards.

	Earnings or Loss Per Common Share Basic earnings or loss per common share is computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share incorporate the incremental shares issuable upon the assumed exercise of stock options and warrants using the treasury stock method. Anti-dilutive options are not included in the computation of diluted earnings per share. Non-vested shares of restricted stock have nonforfeitable dividend rights and are considered participating securities for the purpose of calculating basic and diluted earnings per share under the two-class method.

	Comprehensive Income or Loss There are no items of comprehensive income or loss other than net income or loss.

	Financial Instruments and Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist of cash, cash-equivalents and trade accounts receivable. The Company’s cash-equivalents consist of overnight deposits with federally insured financial institutions. Concentration of credit risk in trade accounts receivable results primarily from sales to major customers. The Company individually evaluates the creditworthiness of its customers and generally does not require collateral or other security. At March 28, 2015, and March 29, 2014, three customers combined accounted for 65% of consolidated gross accounts receivable.

	Fair
Standard Product Warranty, Policy [Policy Text Block]	Accrued Warranty The Company’s warranty policy generally provides one to three years of coverage depending on the product. The Company records a liability for estimated warranty obligations at the date products are sold. The estimated cost of warranty coverage is based on the Company’s actual historical experience with its current products or similar products. For new products, the required reserve is based on historical experience of similar products until such time as sufficient historical data has been collected on the new product. Adjustments are made as new information becomes available.
Inventory, Policy [Policy Text Block]	Inventories Inventories are stated at the lower of cost or fair value using full absorption and standard costing. Cost is determined on a first-in, first-out basis. Standard costing and overhead allocation rates are reviewed by management periodically, but not less than annually. Overhead rates are recorded to inventory based on capacity management expects for the period the inventory will be held. Reserves are recorded within cost of sales for impaired or obsolete inventory when the cost of inventory exceeds its estimated fair value. Management evaluates the need for inventory reserves based on its estimate of the amount realizable through projected sales including an evaluation of whether a product is reaching the end of its life cycle. When inventory is discarded it is written off against the inventory reserve, as inventory generally has already been fully reserved for at the time it is discarded.
Research and Development Expense, Policy [Policy Text Block]	Research and Development Research and development expenditures, which include the cost of materials consumed in research and development activities, salaries, wages and other costs of personnel engaged in research and development, costs of services performed by others for research and development on the Company’s behalf and indirect costs are expensed as operating expenses when incurred. Research and development costs totaled approximately $3.2 million and $3.9 million for the years ended March 28, 2015 and March 29, 2014, respectively.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, which range from three to ten years for machinery and equipment and office fixtures. Leasehold improvements and assets acquired under capital leases are amortized using the straight-line method over the shorter of the estimated useful lives of the respective assets or the lease term.

	The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such review indicates that the carrying amount of an asset exceeds the sum of its expected future cash flows on an undiscounted basis, the asset’s carrying amount would be written down to fair value. Additionally, the Company reports long-lived assets to be disposed of at the lower of carrying amount or fair value less cost to sell. As of March 28, 2015 and March 29, 2014, management believes there has been no impairment of the Company’s long-lived assets.
Derivatives, Policy [Policy Text Block]	Derivatives The Company accounts for free standing derivatives and embedded derivatives required to be bifurcated and accounted for on a stand-alone basis at estimated fair value. Changes in fair value are reported in earnings as other income or loss.
Lease, Policy [Policy Text Block]	Deferred Rent Rent expense is recognized in an amount equal to the guaranteed base rent plus contractual future minimum rental increases amortized on the straight-line basis over the terms of the leases, including free rent periods.
Income Tax, Policy [Policy Text Block]	Income Taxes Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

To date, completion of software development has been concurrent with the establishment of technological feasibility, and accordingly, no costs have been capitalized.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Share-based Compensation The Company has established the 2005 Equity Incentive Plan, which provides for the granting of options for up to 2,250,000 shares of Common Stock. In 2014, the term of the 2005 Equity Incentive Plan was extended to 2025. The Company records share-based compensation expense for the fair value of all stock options and restricted stock that are ultimately expected to vest as the requisite service is rendered.

	The cash flows resulting from the tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) are classified as cash flows from financing in the statements of cash flows.

Diluted earnings per share incorporate the incremental shares issuable upon the assumed exercise of stock options and warrants using the treasury stock method. Anti-dilutive options are not included in the computation of diluted earnings per share. Non-vested shares of restricted stock have nonforfeitable dividend rights and are considered participating securities for the purpose of calculating basic and diluted earnings per share under the two-class method.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income or Loss There are no items of comprehensive income or loss other than net income or loss.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Financial Instruments and Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist of cash, cash-equivalents and trade accounts receivable. The Company’s cash-equivalents consist of overnight deposits with federally insured financial institutions. Concentration of credit risk in trade accounts receivable results primarily from sales to major customers. The Company individually evaluates the creditworthiness of its customers and generally does not require collateral or other security. At March 28, 2015, and March 29, 2014, three customers combined accounted for 65% of consolidated gross accounts receivable.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments and Fair Value Measurements The Company’s financial instruments consist principally of cash and cash-equivalents, line of credit, term debt, warrant liability and warrant derivative liability. The fair value of a financial instrument is the amount at which the instrument could be exchanged in an orderly transaction between market participants to sell the asset or transfer the liability. The Company uses fair value measurements based on quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access as of the measurement date (Level 1), significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data (Level 2), or significant unobservable inputs reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability (Level 3), depending on the nature of the item being valued.

	The carrying amounts of the Company’s cash and cash-equivalents and line of credit approximate their fair values at each balance sheet date due to the short-term maturity of these financial instruments. The fair values of term debt and warrant debt are based on the present value of expected future cash flows and assumptions about current interest rates and the creditworthiness of the Company (Level 3). At March 28, 2015 the carrying amounts of the Company’s term debt and warrant debt totaled $1.1 million and $82,000, respectively. At March 28, 2015 the estimated fair values of the Company’s term debt and warrant debt totaled $1.2 million and $112,000, respectively. At March 29, 2014, the carrying amounts of the Company’s term debt and warrant debt totaled $822,000 and $50,000, respectively, and the carrying amounts approximated fair value since the agreement was entered into near the balance sheet date. The fair value of the bifurcated conversion feature represented by the warrant derivative liability which is measured at fair value on a recurring basis is based on a Black Scholes option pricing model with assumptions for stock price, exercise price, volatility, expected term, risk free interest rate and dividend yield similar to those described previously for share-based compensation which were generally observable (Level 2). The Company had no assets or liabilities measured at fair value on a non-recurring basis, nor were there any transfers between Level 1 and Level 2 of the fair value hierarchy.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards

	In April 2014, the Financial Accounting Standards Board (FASB) issued an accounting standard update that changes the criteria for reporting discontinued operations. Under the accounting standard update, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results when either it qualifies as held for sale, disposed of by sale, or disposed of other than by sale. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2016. The Company is currently evaluating the impact of this accounting standard update on its Consolidated Financial Statements.

	In May 2014, the FASB amended the accounting standards by creating a new Topic 606 which is in response to a joint initiative of the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. generally accepted accounting principles and international financial reporting standards that would:

		1	Remove inconsistencies and weaknesses in revenue requirements.

		2	Provide a more robust framework for addressing revenue issues.

		3	Improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets.

		4	Provide more useful information to users of financial statements through improved disclosure requirements.

		5	Simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer.

	For a public entity, the amendments in this Update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The Company is currently evaluating the impact this new accounting standard will have on its financial statements.

	In June 2014, the FASB amended ASC 718, Share Based Compensation, to require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. For all entities, the amendments in this update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. The Company is currently evaluating the impact this accounting standard update may have on its financial statements.

	In August 2014, the FASB issued ASU 2014-15 which provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. The ASU applies to all entities and is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the impact this accounting standard update may have on its financial statements.

	In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs,” or ASU 2015-03. ASU 2015-03 simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct reduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this ASU. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The adoption of this ASU by the Company will change the presentation of debt issuance costs, which will be reported as a direct offset to the applicable debt on the balance sheet
