ORGANIZATION AND BASIS OF PRESENTATION [Abstract]	'
ORGANIZATION AND BASIS OF PRESENTATION	'
	NOTE 1—ORGANIZATION AND BASIS OF PRESENTATION
	Organization
	GigOptix Inc. (“GigOptix” or the “Company”) is a leading fabless supplier of high speed semiconductor components that enable end-to-end information streaming over optical and wireless networks and address long haul and metro telecommunications applications as well as emerging high-growth opportunities for Cloud and datacenter connectivity, interactive applications for consumer electronics and the industrial, defense and avionics industries.  The business is made up of two product lines: the High-Speed Communications (“HSC”) product line and the Industrial product line.
	The HSC product line offers a broad portfolio of high performance optical and wireless components to telecommunications (“telecom”) and data communications (“datacom”) customers, including (i) mixed signal radio frequency integrated circuits (“RFIC”); (ii) 10 to 400 gigabit per second (“Gbps”) laser and optical drivers and trans-impedance amplifiers (“TIA”) for telecom, datacom, and consumer electronic fiber-optic applications; (iii) power amplifiers and transceivers for microwave and millimeter monolithic microwave integrated circuit (“MMIC”) wireless applications including power amplifiers and transceiver chips at frequencies higher than 50 GHz; (iv) integrated systems in a package (“SIP”) solutions for both fiber-optic and wireless applications; and (v) radio frequency (“RF’) chips for various consumer applications such as global navigation satellite systems (“GNSS”). The HSC product line also partners with key customers on development projects that generate engineering project revenue for the Company while helping to position the Company for future product revenues with these key customers.
	The Industrial product line offers a wide range of digital and mixed-signal application specific integrated circuit (“ASIC”) solutions for industrial, military, avionics, medical and communications markets. The Industrial product line partners with ASIC customers on development projects that generate engineering project revenue for the Company which generally leads to future product revenues with these ASIC customers.
	GigOptix, Inc., the successor to GigOptix LLC, was formed as a Delaware corporation in March 2008 in order to facilitate a combination between GigOptix LLC and Lumera Corporation (“Lumera”). Before the combination, GigOptix LLC acquired the assets of iTerra Communications LLC in July 2007 (“iTerra”) and Helix Semiconductors AG (“Helix”) in January 2008. On November 9, 2009, GigOptix acquired ChipX, Incorporated (“ChipX”). On June 17, 2011, GigOptix acquired Endwave Corporation (“Endwave”). As a result of the acquisitions, Helix, Lumera, ChipX and Endwave all became wholly owned subsidiaries of GigOptix.  In March 2013, the Company established a German subsidiary, GigOptix GmbH; however it is in the process of being dissolved.
	In February 2014, together with Fundação CPqD – Centro De Pesquisa e Desenvolvimento em Telecomunicações (“CPqD”), the Company incepted a new joint venture of which the Company owns 49% and CPqD owns 51%, BrPhotonics Produtos Optoeletrônicos LTDA. (“BrP”), based in Campinas, Brazil, which will be a provider of advanced high-speed devices for optical communications and integrated transceiver components that enable information streaming over communications networks. This joint venture is engaged in research and development of Silicon-Photonics (“SiPh”) advanced electro-optical products.  During the second quarter of 2014, the Company transferred its inventory related to the Thin Film Polymer on Silicon (“TFPSTM”) platform and the production line equipment for use by BrP (see also Note 8).
	In June 2014, the Company signed a definitive agreement to acquire, for cash only by way of assuming specified liabilities, substantially all of the assets of Tahoe RF Semiconductor, Inc. (“Tahoe RF”), a provider of RF/analog RFICs, intellectual property, and fully integrated systems and subsystems on a chip. That acquisition closed on June 30, 2014, which was the first day of the Company’s third quarter of fiscal 2014 (see also Note 4).
	Basis of Presentation
	The Company’s fiscal year ends on December 31. For quarterly reporting, the Company employs a five-week, four-week, four-week, reporting period. The third quarter of 2014 ended on Sunday, September 28, 2014. The third quarter of 2013 ended on Sunday, September 29, 2013. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	The accompanying unaudited condensed consolidated financial statements as of September 28, 2014 and for the three and nine months ended September 28, 2014 and September 29, 2013, have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Article 10 of Securities and Exchange Commission (“SEC”) Regulation S-X, and include the accounts of the Company and all of its subsidiaries. Accordingly, they do not include all of the information and footnotes required by such accounting principles for annual financial statements. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Company’s financial position as of September 28, 2014, the results of operations for the three and nine months ended September 28, 2014 and September 29, 2013, and cash flows for the nine months ended September 28, 2014 and September 29, 2013. The condensed consolidated results of operations for the three and nine months ended September 28, 2014 are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year ending December 31, 2014. It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and the notes thereto included in the Company’s 2013 Form 10-K.
	Use of Estimates
	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reported periods. These judgments can be subjective and complex, and consequently, actual results could differ materially from those estimates and assumptions. Descriptions of these estimates and assumptions are included in the 2013 Form 10-K and the Company encourages you to read its 2013 Form 10-K for more information about such estimates and assumptions.

	Current liabilities:
	Liability warrants	$	15		$	-			$	-		$	15
	The Company’s financial assets and liabilities are valued using market prices on active markets (“Level 1”), less active markets (“Level 2”) and unobservable markets (“Level 3”). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily-available pricing sources for comparable instruments.  Level 3 instruments are valued using unobservable market values in which there is little or no market data, and which require the Company to apply judgment to determine the fair value.
	For the period ended September 28, 2014, the Company did not have any significant transfers between Level 1, Level 2 and Level 3.
	The amounts reported as cash and cash equivalents, accounts receivable, accounts payable, accrued compensation and other current liabilities approximate fair value due to their short-term maturities. The carrying value of the Company’s capital lease obligations approximates fair value and is based upon borrowing rates currently available to the Company for capital leases with similar terms.
	Liability Warrants
	The Company issued warrants to Bridge Bank in connection with a waiver of certain events of default that arose under a November 2009 loan and security agreement with Bridge Bank. Certain provisions in the warrant agreements provided for down-round protection if the Company raised equity capital at a per share price which was less than the per share price of the warrants. Such down-round protection also requires the Company to classify the value of the warrants as a liability on the issuance date and then record changes in the fair value through the consolidated statements of operations for each reporting period until the warrants are either exercised or cancelled. The fair value of the liability is recalculated and adjusted each quarter with the differences being charged to other income (expense), net on the consolidated statements of operations. The fair value of these warrants was determined using a Black-Scholes option-pricing model, which requires the use of significant unobservable market values.  As a result, these warrants are classified as Level 3 financial instruments. On July 7, 2010, the Company raised additional equity through an offering of 2,760,000 shares at $1.75 per share, thus triggering the down-round protection and adjustment of the number of warrants issued to Bridge Bank. On December 24, 2013, the Company raised additional equity through an offering of 9,573,750 shares at $1.42 per share, thus triggering the down-round protection and adjustment of the number of warrants issued to Bridge Bank.
	The fair value of the warrants was estimated using the following assumptions:
		As of September 28, 2014			As of December 31, 2013
	Stock price	$	1.19		$	1.53
	Strike price	$	2.51		$	2.51
	Expected life	2.80 years			3.55 years
	Risk-free interest rate		1.08	%		1.3	%
	Volatility		65	%		65	%
	Fair value per share	$	0.26		$	0.52
	The following table summarizes the warrants subject to liability accounting as of September 28, 2014 and December 31, 2013 (in thousands, except share and per share amounts) (see also Note 6):

	On March 25, 2013, the Company entered into a second amended and restated loan and security agreement (“Loan Agreement”) with Silicon Valley Bank (“SVB”) to replace the amended and restated loan and security agreement entered on December 9, 2011. Pursuant to the Loan Agreement, the total aggregate amount that the Company is entitled to borrow from SVB has increased to $7 million, which is now split into two different credit facilities, comprised of (i) the existing Revolving Loan facility which was amended to provide that the Company is entitled to borrow from SVB up to $3.5 million, based on net eligible accounts receivable after an 80% advance rate and subject to limits based on the Company’s eligible accounts as determined by SVB and (ii) a new facility under which the Company is entitled to borrow from SVB up to $3.5 million without reference to accounts receivable under which the principal balance and accrued interest must be repaid within 3 business days after the date of any advance under the facility. In addition, the Loan Agreement eliminates the financial covenants contained in the previous loan agreement.
	The Loan Agreement with SVB is secured by all of the Company’s assets, including all accounts, equipment, inventory, receivables, and general intangibles. The Loan Agreement contains certain restrictive covenants that will impose significant operating and financial restrictions on its operations, including, but not limited to restrictions that limit its ability to:

	Public Offering
	On December 19, 2013, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Roth Capital Partners, LLC as representative of several underwriters to the Underwriting Agreement relating to a public offering of an aggregate of 8,325,000 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share at a public offering price of $1.42 per share. The Shares are accompanied by the associated rights to purchase shares of Series A Junior Preferred Stock, par value $0.001 per share, of the Company created by the Rights Agreement, dated December 16, 2011, between the Company and the American Stock Transfer & Trust Company, LLC, as Rights Agent (the “Rights Agreement”).  Under the terms of the Underwriting Agreement, the Company granted the Underwriters a 30 day option to purchase up to an additional 1,248,750 shares of common stock to cover over-allotments.
	On December 24, 2013, the Company completed its public offering of 9,573,750 newly issued shares of common stock at a price to the public of $1.42 per share. The number of shares sold in the offering included the underwriter’s full exercise on December 24, 2013 of their over-allotment option of 1,248,750 shares of common stock. The net proceeds to the Company from the offering was approximately $12.3 million which consisted of $12.5 million after underwriting discounts, commissions and expenses less an additional $250,000 for legal, accounting, registration and other transaction costs related to the public offering.
	Common and Preferred Stock
	In December 2008, the Company’s stockholders approved an amendment to the Certificate of Incorporation to authorize 50,000,000 shares of common stock of par value $0.001. In addition, the Company is authorized to issue 1,000,000 shares of preferred stock of $0.001 par value of which 300,000 shares have been designated Series A Junior Preferred Stock with powers, preferences and rights as set forth in the certificate of designation dated December 16, 2011; the remainder of the shares of preferred stock are undesignated, for which the Board of Directors is authorized to fix the designation, powers, preferences and rights. As of September 28, 2014 and December 31, 2013, there were no shares of preferred stock issued or outstanding.
	2008 Equity Incentive Plan
	In December 2008, the Company adopted the 2008 Equity Incentive Plan (the “2008 Plan”) for directors, employees, consultants and advisors to the Company or its affiliates. Under the 2008 Plan, 2,500,000 shares of common stock were reserved for issuance upon the completion of a merger with Lumera Corporation (“Lumera”) on December 9, 2008. On January 1 of each year, starting in 2009, the aggregate number of shares reserved for issuance under the 2008 Plan increase automatically by the lesser of: (i) 5% of the number of shares of common stock outstanding as of the Company’s immediately preceding fiscal year, or (ii) a number of shares determined by the Board of Directors. The maximum number of shares of common stock to be granted is up to 21,000,000 shares. Forfeited options or awards generally become available for future awards.  As of December 31, 2013, the stockholders had approved 15,021,253 shares for future issuance. On January 1, 2014, there was an automatic increase of 1,603,381 shares. As of September 28, 2014, 10,664,161 options to purchase common stock and restricted stock were outstanding and 3,511,707 shares are authorized for future issuance under the 2008 equity incentive plan.
	Under the 2008 Plan, the exercise price of a stock option is at least 100% of the stock’s fair market value on the date of grant, and if an ISO is granted to a 10% stockholder at least 110% of the stock’s fair market value on the date of grant. Vesting periods for awards are recommended by the chief executive officer and generally provide for stock options to vest over a four-year period, with a one year vesting cliff of 25%, and have a maximum life of ten years from the date of grant. The Company has also issued restricted stock units (“RSUs”) which generally vest over a one to four-year period.
	2007 Equity Incentive Plan
	In August 2007, GigOptix LLC adopted the GigOptix LLC Equity Incentive Plan (the "2007 Plan"). The 2007 Plan provided for grants of options to purchase membership units, membership awards and restricted membership units to employees, officers and non-employee directors, and upon the completion of the merger with Lumera were converted into grants of up to 632,500 shares of stock. Vesting periods are determined by the Board of Directors and generally provide for stock options to vest over a four-year period and expire ten years from date of grant. Vesting for certain shares of restricted stock is contingent upon both service and performance criteria. The 2007 Plan was terminated upon the completion of merger with Lumera on December 9, 2008 and the remaining 864 stock options not granted under the 2007 Plan were cancelled. No shares of the Company’s common stock remain available for issuance of new grants under the 2007 Plan other than for satisfying exercises of stock options granted under this plan prior to its termination. As of September 28, 2014, options to purchase a total of 376,436 shares of common stock and 4,125 warrants to purchase common stock were outstanding.
	Lumera 2000 and 2004 Stock Option Plan
	In December 2008, in connection with the merger with Lumera, the Company assumed the existing Lumera 2000 Equity Incentive Plan and the Lumera 2004 Stock Option Plan (the “Lumera Plan”). All unvested options granted under the Lumera Plan were assumed by the Company as part of the merger. All contractual terms of the assumed options remain the same, except for the converted number of shares and exercise price based on merger conversion ratio of 0.125. As of September 28, 2014, no additional options can be granted under the Lumera Plan, and options to purchase a total of 66,428 shares of common stock were outstanding.
	Warrants
	As of December 31, 2013, the Company had a total of 1,468,239 warrants to purchase common stock outstanding under all warrant arrangements. During the nine months ended September 28, 2014, no warrants were exercised and 809,999 warrants expired. As a result, as of September 28, 2014, the Company had 658,240 warrants to purchase common stock outstanding under all warrant arrangements. Some of the warrants have anti-dilution provisions which adjust the number of warrants available to the holder such as, but not limited to, stock dividends, stock splits and certain reclassifications, exchanges, combinations or substitutions. These provisions are specific to each warrant agreement.
	Stock-based Compensation Expense
	The following table summarizes the Company’s stock-based compensation expense for the three and nine months ended September 28, 2014 and September 29, 2013 (in thousands):
		Three Months Ended					Nine Months Ended

	For the nine months ended September 28, 2014, included in the $3.2 million of stock-based compensation expense is $9,000 in restructuring expense to modify the exercise period and accelerate the vesting of RSUs (see Note 7).
	For the nine months ended September 29, 2013, included in the $3.3 million of stock-based compensation expense is $662,000 in restructuring expense to modify the exercise period and accelerate the vesting of stock options and RSUs (see Note 7).
	During the three months ended September 29, 2013, the Company granted options to purchase 35,000 of common stock with an estimated total grant-date fair value of $32,000 or $0.91 per share. During the three months ended September 28, 2014, the Company did not issue any option grants.
	During the three months ended September 28, 2014 and September 29, 2013, the Company granted 135,000 and 1,008,527 RSUs, respectively, with a grant-date fair value of $185,000 or $1.37 per share and $1.3 million or $1.33 per share, respectively.
	During the nine months ended September 28, 2014 and September 29, 2013, the Company granted options to purchase 25,000 and 645,010 of common stock, respectively, with an estimated total grant-date fair value of $28,000 or $1.10 per share and $391,000 or $0.61 per share, respectively.
	During the nine months ended September 28, 2014 and September 29, 2013, the Company granted 1,610,085 and 1,578,373 RSUs, respectively, with a grant-date fair value of $2.7 million or $1.67 per share and $1.8 million or $1.16 per share, respectively.
	As of September 28, 2014, the total compensation cost not yet recognized in connection with unvested stock options and RSUs under the Company’s equity compensation plans was approximately $2.0 million and $2.4 million, respectively. Unrecognized compensation will be amortized on a straight-line basis over a weighted-average period of approximately 1.50 years for stock options and approximately 2.45 years for RSUs.
	Stock Option and RSU Activity
	The following is a summary of option activity for the Company’s equity incentive plans, including both the 2008 Plan and other prior plans for which there are outstanding options but no new grants since the 2008 Plan was adopted:
		Options			Weighted-		Weighted-
					Average		Average
					Exercise Price		Remaining
							Contractual

	Outstanding, December 31, 2013		10,306,671		$	2.34		6.96
	Granted		25,000			1.59
	Exercised		(225,678	)		1.02
	Forfeited/Expired		(999,546	)		2.51
	Ending balance, September 28, 2014		9,106,447		$	2.35		6.2
	Vested and exercisable and expected to vest, September 28, 2014		9,001,301		$	2.35		6.19
	Vested and exercisable, September 28, 2014		7,562,900		$	2.37		5.93
	The aggregate intrinsic value of options vested, exercisable and expected to vest, based on the fair value of the underlying stock options as of September 28, 2014 was approximately $459,000. The aggregate intrinsic value reflects the difference between the exercise price of the underlying stock options and the Company’s closing share price of $1.19 as of September 26, 2014.
	The total intrinsic value of options exercised during the nine months ended September 28, 2014 and September 29, 2013 was approximately $84,000 and $1,000, respectively.
	RSUs are converted into shares of the Company’s common stock upon vesting on a one-for-one basis. Typically, vesting of RSUs is subject to the employee’s continuing service to the Company. RSUs generally vest over a period of one to four years and are expensed ratably on a straight line basis over their respective vesting period net of estimated forfeitures. The fair value of the RSUs granted is the product of the number of shares granted and the grant date fair value of the Company’s common stock.
	The following is a summary of restricted stock unit activity for the indicated periods:
		Number of			Weighted-		Weighted-		Aggregate
		Shares			Average Grant		Average		Intrinsic
					Date Fair Value		Remaining		Value
							Vesting Term,
							Years
									(in thousands)
	Outstanding, December 31, 2013		1,313,801		$	1.19		1.85	$	2,010
	Granted		1,610,085			1.67
	Released		(815,526	)		1.33
	Forfeited/expired		(107,782	)		1.43
	Outstanding, September 28, 2014		2,000,578		$	1.51		2.45	$	2,381
	The majority of the RSUs that vested in the nine months ended September 28, 2014 were net-share settled such that the Company withheld shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. The total shares withheld were based on the value of the RSUs on their vesting date as determined by the Company’s closing stock price. These net-share settlements had the effect of share repurchases by the Company as they reduced and retired the number of shares that would have otherwise been issued as a result of the vesting and did not represent an expense to the Company. For the nine months ended September 28, 2014, 815,526 shares of RSUs vested with an intrinsic value of approximately $970,000. The Company withheld 249,000 shares to satisfy approximately $378,000 of employees’ minimum tax obligation on the vested RSUs.

	In February 2014, together with CPqD, the Company incepted a new joint venture, named BrP, of which the Company owns 49% and CPqD owns 51% of BrP. It is based in Campinas, Brazil. BrP will be a provider of advanced high-speed devices for optical communications and integrated transceiver components for information networks. It is engaged in research and development of SiPh advanced electro-optical products.
	The Company transferred into BrP its knowledge-base and intellectual property of TFPSTM technology. The Company transferred to CPqD, its inventory related to the TFPSTM platform and the complete production line equipment that previously resided at its Bothell, Washington, facility for CPqD to use for the BrP joint venture. As of the transfer date, the Company’s net book value of the inventory and property and equipment was $245,000 and $211,000, respectively, which resulted in a $456,000 investment in BrP.
	For the three and nine months ended September 28, 2014, the Company’s allocated portion of BrP’s results was a loss of $125,000 and $456,000, respectively. Since the Company’s share of the loss exceeded the Company’s carrying cost of its investment in BrP, the Company’s investment in an unconsolidated affiliate was written down to zero as of September 28, 2014.

	NOTE 9—INCOME TAXES
	The Company recorded a provision for income taxes of $8,000 and $39,000 for the three and nine months ended September 28, 2014, respectively, and $1,000 and $28,000 for the three and nine months ended September 29, 2013, respectively. The Company's effective tax rate was less than 1% for the three and nine months ended September 28, 2014 and September 29, 2013.
	The income tax provision for the three and nine months ended September 28, 2014 and September 29, 2013 was due primarily to state taxes and foreign taxes due. The Company has incurred book losses in all tax jurisdictions and has a full valuation allowance against such losses.
	In assessing the potential realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. In making such a determination, management considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial performance. In order to support a conclusion that a valuation allowance is not needed, positive evidence of sufficient quantity and quality is necessary to overcome negative evidence. The ultimate realization of deferred tax assets is dependent on the generation of future taxable income during the periods in which those temporary differences become deductible. A valuation allowance has been recorded for the entire deferred tax asset as a result of uncertainties regarding realization of the asset including lack of profitability through September 28, 2014 and the uncertainty over future operating profitability and taxable income. The Company will continue to evaluate the potential realization of the deferred tax assets on a quarterly basis.
	The Company files tax returns as prescribed by the tax laws of the jurisdictions it operates which include U.S. federal, U.S. state and foreign tax returns. The Company’s major tax jurisdictions are the U.S., California, Switzerland, Germany and Israel. The Company’s federal and state tax returns for the years 2000 through 2013 remain subject to examination.

	NOTE 14—RECENT ACCOUNTING PRONOUNCEMENTS
	In June 2014, the Financial Accounting Standard Board (“FASB”) issued an accounting standard update clarifying the accounting guidance on how to account for share-based payment awards that require a specific performance target to be achieved in order for employees to become eligible to vest in the awards. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. This standard is effective for periods beginning after December 15, 2015 and early adoption is permitted. The Company does not expect the adoption will have a material impact on the Company’s condensed consolidated financial statements.
	In May 2014, the FASB issued an accounting standard clarifying the principles for recognizing revenue by amending the FASB Accounting Standards Codification and creating a new Topic 606, Revenue from Contracts with Customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This standard is effective for annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. The Company is currently evaluating the impact of the adoption on the Company’s condensed consolidated financial statements.

ORGANIZATION AND BASIS OF PRESENTATION [Abstract]	'
Organization	'
	Organization
	GigOptix Inc. (“GigOptix” or the “Company”) is a leading fabless supplier of high speed semiconductor components that enable end-to-end information streaming over optical and wireless networks and address long haul and metro telecommunications applications as well as emerging high-growth opportunities for Cloud and datacenter connectivity, interactive applications for consumer electronics and the industrial, defense and avionics industries.  The business is made up of two product lines: the High-Speed Communications (“HSC”) product line and the Industrial product line.
	The HSC product line offers a broad portfolio of high performance optical and wireless components to telecommunications (“telecom”) and data communications (“datacom”) customers, including (i) mixed signal radio frequency integrated circuits (“RFIC”); (ii) 10 to 400 gigabit per second (“Gbps”) laser and optical drivers and trans-impedance amplifiers (“TIA”) for telecom, datacom, and consumer electronic fiber-optic applications; (iii) power amplifiers and transceivers for microwave and millimeter monolithic microwave integrated circuit (“MMIC”) wireless applications including power amplifiers and transceiver chips at frequencies higher than 50 GHz; (iv) integrated systems in a package (“SIP”) solutions for both fiber-optic and wireless applications; and (v) radio frequency (“RF’) chips for various consumer applications such as global navigation satellite systems (“GNSS”). The HSC product line also partners with key customers on development projects that generate engineering project revenue for the Company while helping to position the Company for future product revenues with these key customers.
	The Industrial product line offers a wide range of digital and mixed-signal application specific integrated circuit (“ASIC”) solutions for industrial, military, avionics, medical and communications markets. The Industrial product line partners with ASIC customers on development projects that generate engineering project revenue for the Company which generally leads to future product revenues with these ASIC customers.
	GigOptix, Inc., the successor to GigOptix LLC, was formed as a Delaware corporation in March 2008 in order to facilitate a combination between GigOptix LLC and Lumera Corporation (“Lumera”). Before the combination, GigOptix LLC acquired the assets of iTerra Communications LLC in July 2007 (“iTerra”) and Helix Semiconductors AG (“Helix”) in January 2008. On November 9, 2009, GigOptix acquired ChipX, Incorporated (“ChipX”). On June 17, 2011, GigOptix acquired Endwave Corporation (“Endwave”). As a result of the acquisitions, Helix, Lumera, ChipX and Endwave all became wholly owned subsidiaries of GigOptix.  In March 2013, the Company established a German subsidiary, GigOptix GmbH; however it is in the process of being dissolved.
	In February 2014, together with Fundação CPqD – Centro De Pesquisa e Desenvolvimento em Telecomunicações (“CPqD”), the Company incepted a new joint venture of which the Company owns 49% and CPqD owns 51%, BrPhotonics Produtos Optoeletrônicos LTDA. (“BrP”), based in Campinas, Brazil, which will be a provider of advanced high-speed devices for optical communications and integrated transceiver components that enable information streaming over communications networks. This joint venture is engaged in research and development of Silicon-Photonics (“SiPh”) advanced electro-optical products.  During the second quarter of 2014, the Company transferred its inventory related to the Thin Film Polymer on Silicon (“TFPSTM”) platform and the production line equipment for use by BrP (see also Note 8).
	In June 2014, the Company signed a definitive agreement to acquire, for cash only by way of assuming specified liabilities, substantially all of the assets of Tahoe RF Semiconductor, Inc. (“Tahoe RF”), a provider of RF/analog RFICs, intellectual property, and fully integrated systems and subsystems on a chip. That acquisition closed on June 30, 2014, which was the first day of the Company’s third quarter of fiscal 2014 (see also Note 4).
Basis of Presentation	'
	Basis of Presentation
	The Company’s fiscal year ends on December 31. For quarterly reporting, the Company employs a five-week, four-week, four-week, reporting period. The third quarter of 2014 ended on Sunday, September 28, 2014. The third quarter of 2013 ended on Sunday, September 29, 2013. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	The accompanying unaudited condensed consolidated financial statements as of September 28, 2014 and for the three and nine months ended September 28, 2014 and September 29, 2013, have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Article 10 of Securities and Exchange Commission (“SEC”) Regulation S-X, and include the accounts of the Company and all of its subsidiaries. Accordingly, they do not include all of the information and footnotes required by such accounting principles for annual financial statements. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Company’s financial position as of September 28, 2014, the results of operations for the three and nine months ended September 28, 2014 and September 29, 2013, and cash flows for the nine months ended September 28, 2014 and September 29, 2013. The condensed consolidated results of operations for the three and nine months ended September 28, 2014 are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year ending December 31, 2014. It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and the notes thereto included in the Company’s 2013 Form 10-K.
Use of Estimates	'
	Use of Estimates
	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reported periods. These judgments can be subjective and complex, and consequently, actual results could differ materially from those estimates and assumptions. Descriptions of these estimates and assumptions are included in the 2013 Form 10-K and the Company encourages you to read its 2013 Form 10-K for more information about such estimates and assumptions.
