Business Combinations [Abstract]
BUSINESS ACQUISITION	BUSINESS ACQUISITIONS During fiscal 2020, the Company completed the acquisitions of Active-Semi International, Inc. ("Active-Semi"), Cavendish Kinetics Limited ("Cavendish"), Custom MMIC Design Services, Inc. ("Custom MMIC") and Decawave Limited ("Decawave"). The operating results of these companies have been included in the Company's consolidated financial statements as of their acquisition dates. Active-Semi International, Inc. On May 6, 2019, the Company acquired all of the outstanding equity interests of Active-Semi, a private fabless supplier of programmable analog power management solutions, for a total purchase price of $307.9 million. The acquisition expanded the Company's product offerings in power management markets. During the three months ended June 27, 2020, the Company recognized an increase to goodwill of approximately $0.1 million in connection with finalizing the purchase price allocation. The measurement period ended one year from the acquisition date. Cavendish Kinetics Limited Prior to fiscal 2020, the Company had an investment in preferred shares in Cavendish, a private supplier of high-performance radio frequency ("RF") microelectromechanical system ("MEMS") technology for antenna tuning applications, with a carrying value of $59.4 million. The Company accounted for this investment as an equity investment without a readily determinable fair value using the measurement alternative in accordance with ASC 321, "Investments-Equity Securities." On October 4, 2019, the Company acquired the remaining issued and outstanding capital of Cavendish for cash consideration of $198.4 million. The acquisition advances RF MEMS technology for applications across the Company's products and the technology will be transitioned into high-volume manufacturing for mobile devices and other markets. The purchase of the remaining equity interest in Cavendish was considered to be an acquisition achieved in stages, whereby the previously held equity interest was remeasured at its acquisition-date fair value. The Company determined that the fair value of its previously held equity investment was $102.4 million based on the purchase consideration exchanged to acquire the remaining issued and outstanding capital of Cavendish, which resulted in recognition of a gain of $43.0 million in fiscal 2020. During the three months ended June 27, 2020, the Company recognized an increase to goodwill of approximately $1.5 million and a decrease to intangibles of approximately $2.0 million as a result of purchase price allocation adjustments. The Company will continue to evaluate certain assets, liabilities, and tax estimates over the measurement period (up to one year from the October 4, 2019 acquisition date). Custom MMIC Design Services, Inc. On February 6, 2020, the Company acquired all of the outstanding equity interests of Custom MMIC, a supplier of high-performance gallium arsenide ("GaAs") and gallium nitride ("GaN") monolithic microwave integrated circuits ("MMICs") for defense and commercial applications, for a total purchase price of $91.7 million. The acquisition expands the Company's millimeter wave ("mmWave") capabilities for product offerings in defense and commercial markets. On the acquisition date, the purchase price was comprised of cash consideration of $86.0 million and contingent consideration of $5.7 million (based on estimated fair value) which is payable to the sellers in the first quarter of fiscal 2022 if certain revenue targets are achieved over a one-year period from the acquisition date. At June 27, 2020, the contingent consideration liability was remeasured to fair value ($9.6 million, which is included in "Accrued liabilities") with changes recognized in "Other operating expense.” See Note 6 for further information related to the fair value measurement. During the three months ended June 27, 2020, the Company recognized a decrease to goodwill of approximately $0.5 million as a result of purchase price allocation adjustments. The Company will continue to evaluate certain assets, liabilities, and tax estimates over the measurement period (up to one year from the acquisition date). Decawave Limited On February 21, 2020, the Company acquired all of the outstanding equity interests of Decawave, a pioneer in ultra-wide band ("UWB") technology and provider of UWB solutions for mobile, automotive and Internet of Things ("IoT") applications, for a total purchase price of $372.7 million. The acquisition expands the Company's product and technology offerings that enables real-time, highly accurate and reliable local area precision-location services. During the three months ended June 27, 2020, the Company recognized a decrease to goodwill of approximately $2.3 million as a result of purchase price allocation adjustments. The Company will continue to evaluate certain assets, liabilities, and tax estimates over the measurement period (up to one year from the acquisition date).
