Variable Interest Entity [Abstract]
Variable Interest Entity (VIE)	Variable Interest Entity (VIE) The Company follows authoritative guidance for the consolidation of a VIE, which requires an enterprise to determine whether its variable interest gives it a controlling financial interest in a VIE. Determination about whether an enterprise should consolidate a VIE is required to be evaluated continuously as changes to existing relationships or future transactions may result in consolidating or deconsolidating the VIE. Cercacor Cercacor is an independent entity spun off from the Company to its stockholders in 1998. Joe Kiani, the Company’s Chairman and Chief Executive Officer (CEO), is also the Chairman and CEO of Cercacor. The Company is a party to a Cross-Licensing Agreement with Cercacor, which was most recently amended and restated effective January 1, 2007 (the Cross-Licensing Agreement), that governs each party’s rights to certain intellectual property held by the two companies. In addition, the Company entered into a Services Agreement with Cercacor effective January 1, 2007, which governs the general and administrative services the Company provides to Cercacor. As a result of recent changes in the capital structure of Cercacor, as well as certain of its contractual relationships with the Company, the Company completed a re-evaluation of the authoritative consolidation guidance during the first quarter of 2016 and determined that although Cercacor remains a VIE, the Company is no longer its primary beneficiary as it can no longer be deemed to have the power to direct the activities of Cercacor that most significantly impact Cercacor’s economic performance and can no longer be deemed to have an obligation to absorb Cercacor’s losses pursuant to the Company’s on-going contractual relationships with Cercacor. Based on such determination, the Company discontinued consolidating Cercacor within its consolidated financial statements effective as of January 3, 2016. However, Cercacor continues to be a related party following its deconsolidation. The Company recognized a gain of $0.3 million upon such deconsolidation, which has been reported within non-operating income in the condensed consolidated statement of operations. See Note 4 to these condensed consolidated financial statements for a description of the Company’s continuing business relationships with Cercacor. Cercacor continues to be included within the Company’s condensed consolidated financial statements for all periods prior to January 3, 2016. Accordingly, for periods prior to January 3, 2016, all intercompany royalties, option and license fees and other charges between the Company and Cercacor, as well as all intercompany payables and receivables, have been eliminated in consolidation. However, for periods prior to January 3, 2016, all direct operating expenses that were incurred by the Company and charged to Cercacor, or that were incurred by Cercacor and charged to the Company, have not been eliminated and are included within operating expenses in the Company’s condensed consolidated statements of operations. The consolidating statement of operations for the three and nine months ended October 3, 2015, which reflect the Company, Cercacor and related eliminations (in thousands), is included below: Cercacor Cercacor is an independent entity spun off from the Company to its stockholders in 1998.
