BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2:    BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The interim condensed consolidated financial statements have been prepared according to U.S Generally Accepted Accounting Principles (“U.S. GAAP”).
	The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. For further information, reference is made to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
	The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2014, contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 13, 2015, have been applied consistently in these unaudited interim condensed consolidated financial statements.
	Use of Estimates
	The preparation of the interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the dates of the interim condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

ACQUISITION OF RIVIERAWAVES	NOTE 3:	ACQUISITION OF RIVIERAWAVES
	On July 4, 2014 (the “Closing Date”), the Company acquired 100% of RivieraWaves SAS (“RivieraWaves”), a privately-held, French-based company and a provider of wireless connectivity intellectual property for Wi-Fi and Bluetooth technologies. The Company agreed to pay an aggregate of $18,378 to acquire RivieraWaves with $14,678 paid on the Closing Date and the remaining amount of $3,700 payable upon the satisfaction of certain milestones (the “Contingent Consideration”). During the first quarter of 2015, the Company paid $2,700 of the Contingent Consideration, and the remaining amount of $1,000 is expected to be paid during the remainder of 2015. The Contingent Consideration is recognized as a liability at fair value. As of March 31, 2015, the fair value of the Contingent Consideration was estimated to be $951. Accretion of the Contingent Consideration liability is included in financial income, net.
	The acquisition has been accounted in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) No. 805, “Business Combinations.”
	In addition, as part of the acquisition, the Company established an employee retention plan for the RivieraWaves employees at a cost of approximately $3,400, to be payable on a semi-annual basis for a period of two years after the Closing Date. As of March 31, 2015, the Company paid $329 of the employee retention plan.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	NOTE 5:    FAIR VALUE MEASUREMENT
	FASB ASC No. 820, “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value. Fair value is an exit price, representing the amount that would be received for selling an asset or paid for the transfer of a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value:
	Level I	Unadjusted quoted prices in active markets that are accessible on the measurement date for identical, unrestricted assets or liabilities;
	Level II	Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
	Level III	Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).
	The Company measures its marketable securities, foreign currency derivative contracts and the Contingent Consideration at fair value. Marketable securities and foreign currency derivative contracts are classified within Level II as the valuation inputs are based on quoted prices and market observable data of similar instruments. The Contingent Consideration related to the RivieraWaves acquisition is classified within Level III as it is based on significant inputs not observable in the market.
	The table below sets forth the Company’s assets and liabilities measured at fair value by level within the fair value hierarchy. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

COMMON STOCK AND STOCK-BASED COMPENSATION PLANS	NOTE 8:	COMMON STOCK AND STOCK-BASED COMPENSATION PLANS
	The Company grants stock options and stock appreciation rights (“SARs”) capped with a ceiling to employees and stock options to non-employee directors of the Company and its subsidiaries and provides the right to purchase common stock pursuant to the Company’s 2002 employee stock purchase plan to employees of the Company and its subsidiaries. The SAR unit confers the holder the right to stock appreciation over a preset price of the Company’s common stock during a specified period of time. When the unit is exercised, the appreciation amount is paid through the issuance of shares of the Company’s common stock. The ceiling limits the maximum income for each SAR unit. SARs are considered an equity instrument as it is a net share settled award capped with a ceiling (400% for SAR grants made during the three months ended March 31, 2015). The options and SARs granted under the Company’s stock incentive plans have been granted at the fair market value of the Company’s common stock on the grant date. Options and SARs granted to employees under stock incentive plans vest at a rate of 25% of the shares underlying the option after one year and the remaining shares vest in equal portions over the following 36 months, such that all shares are vested after four years. Options granted to non-employee directors vest 25% of the shares underlying the option on each anniversary of the option grant. A summary of the Company’s stock option and SARs activities and related information for the three months ended March 31, 2015, are as follows:
			Number of			Weighted		Weighted
			options and			average		average		Aggregate
			SAR units			exercise		remaining		intrinsic-

	Exercisable as of March 31, 2015 (3)			1,690,821		$	18.17		3.5	$	8,100,340
	-1	The SAR units are convertible for a maximum number of shares of the Company’s common stock equal to 75% of the SAR units subject to the grant.
	-2	Due to the ceiling imposed on the SAR grants, the outstanding amount equals a maximum of 2,524,973 shares of the Company’s common stock issuable upon exercise.
	-3	Due to the ceiling imposed on the SAR grants, the exercisable amount equals a maximum of 1,548,456 shares of the Company’s common stock issuable upon exercise.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	NOTE 9:	DERIVATIVES AND HEDGING ACTIVITIES
	The Company follows the requirements of FASB ASC No. 815,” Derivatives and Hedging” which requires companies to recognize all of their derivative instruments as either assets or liabilities in the statement of financial position at fair value. The accounting for changes in fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging transaction and further, on the type of hedging transaction. For those derivative instruments that are designated and qualify as hedging instruments, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation. Due to the Company’s global operations, it is exposed to foreign currency exchange rate fluctuations in the normal course of its business. The Company’s treasury policy allows it to offset the risks associated with the effects of certain foreign currency exposures through the purchase of foreign exchange forward or option contracts (“Hedging Contracts”). The policy, however, prohibits the Company from speculating on such Hedging Contracts for profit. To protect against the increase in value of forecasted foreign currency cash flow resulting from salaries paid in currencies other than the U.S. dollar during the year, the Company instituted a foreign currency cash flow hedging program. The Company hedges portions of the anticipated payroll of its non-U.S. employees denominated in the currencies other than the U.S. dollar for a period of one to twelve months with Hedging Contracts. Accordingly, when the dollar strengthens against the foreign currencies, the decline in present value of future foreign currency expenses is offset by losses in the fair value of the Hedging Contracts. Conversely, when the dollar weakens, the increase in the present value of future foreign currency expenses is offset by gains in the fair value of the Hedging Contracts. These Hedging Contracts are designated as cash flow hedges.
	For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Any gain or loss on a derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item is recognized in current earnings during the period of change. As of March 31, 2015 and December 31, 2014, the notional principal amount of the Hedging Contracts to sell U.S. dollars held by the Company was $9,500 and $4,200, respectively.
	The fair value of the Company’s outstanding derivative instruments is as follows:

SHARE REPURCHASE PROGRAM	NOTE 11:	SHARE REPURCHASE PROGRAM
	During the first quarter of 2015, the Company repurchased 93,903 shares of common stock at an average purchase price of $20.41 per share for an aggregate purchase price of $1,917. During the first quarter of 2014, the Company repurchased 235,619 shares of common stock at an average purchase price of $17.51 per share for an aggregate purchase price of $4,127. As of March 31, 2015, 906,097 shares of common stock remained available for repurchase pursuant to the Company’s share repurchase program.
	The repurchases of common stock are accounted for as treasury stock, and result in a reduction of stockholders’ equity. When treasury shares are reissued, the Company accounts for the reissuance in accordance with FASB ASC No. 505-30, “Treasury Stock” and charges the excess of the repurchase cost over issuance price using the weighted average method to retained earnings. The purchase cost is calculated based on the specific identified method. In the case where the repurchase cost over issuance price using the weighted average method is lower than the issuance price, the Company credits the difference to additional paid-in capital.

	In May 2014, the Financial Accounting Standards Board issued guidance related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace most existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is not permitted. The updated standard will be effective for the Company in the first quarter of 2017. The Company has not yet selected a transition method, and it is currently evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.

Basis of Presentation	Basis of Presentation
	The interim condensed consolidated financial statements have been prepared according to U.S Generally Accepted Accounting Principles (“U.S. GAAP”).
	The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. For further information, reference is made to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
	The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2014, contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 13, 2015, have been applied consistently in these unaudited interim condensed consolidated financial statements.
Use of Estimates	Use of Estimates
	The preparation of the interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the dates of the interim condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Impact of Recently Issued Accounting Standards Not Yet Adopted	In May 2014, the Financial Accounting Standards Board issued guidance related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace most existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is not permitted. The updated standard will be effective for the Company in the first quarter of 2017. The Company has not yet selected a transition method and it is currently evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.
