CUSIP NO. 89674K103

The following constitutes Amendment No. 5 (“Amendment No. 5”) to the Schedule 13D filed by the undersigned. This Amendment No. 5 amends the Schedule 13D as specifically set forth.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

The Shares purchased by each of Starboard V&O Fund, Starboard S LLC, Starboard C LP and Alpha LLC and held in the Starboard Value LP Account were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market purchases, except as otherwise noted. The aggregate purchase price of the 2,109,686 Shares beneficially owned by Starboard V&O Fund is approximately $9,690,415, excluding brokerage commissions. The aggregate purchase price of the 516,745 Shares beneficially owned by Starboard S LLC is approximately $3,955,210, excluding brokerage commissions. The aggregate purchase price of the 309,581 Shares beneficially owned by Starboard C LP is approximately $1,425,082, excluding brokerage commissions. The aggregate purchase price of the 712,777 Shares beneficially owned by Alpha LLC is approximately $3,425,580, excluding brokerage commissions. The aggregate purchase price of the 812,689 Shares held in the Starboard Value LP Account is approximately $5,936,506, excluding brokerage commissions.

The Shares purchased by each of Messrs. Khan, Hill, Phelan and Wills were purchased in the open market with personal funds. The aggregate purchase price of the 20,000 Shares owned directly by Mr. Khan is approximately $125,892, excluding brokerage commissions. The aggregate purchase price of the 309 Shares owned directly by Mr. Hill is approximately $2,435, excluding brokerage commissions. The aggregate purchase price of the 610 Shares owned directly by Mr. Phelan is approximately $4,904, excluding brokerage commissions. The aggregate purchase price of the 1,000 Shares owned directly by Mr. Wills is approximately $8,030, excluding brokerage commissions.

Item 4.

Purpose of the Transaction.

Item 4 is hereby amended to add the following:

Starboard Value LP and its affiliates (collectively, “Starboard”) believe the Issuer’s announcement to merge with RF Micro Devices, Inc. (“RFMD”) and form a new company (“NewCo”) is in the best interests of shareholders and has the potential to create substantial long-term value. Starboard has conducted significant diligence on both the Issuer and RFMD as well as the announced merger. Starboard’s analysis demonstrates that the synergies for both companies are far higher than the $150 million that has been publicly committed. In fact, Starboard’s analysis demonstrates that the synergies between the Issuer and RFMD should be between $200 million and $250 million through a combination of R&D and SG&A savings, test and assembly savings, and facility consolidation. Further, to the extent that the current RFMD merger closes, Starboard believes that there is an opportunity to combine the Issuer’s Networks & Defense business with parts of RFMD’s Multi-Market Products Group to create a leader in the niche ultra-high-end GaAs and GaN semiconductor market for military, defense and networking applications, which in Starboard’s opinion would trade at a substantially higher multiple than where the Issuer or RFMD currently trade. Starboard also believes this new business could either be spun out as an independent public company, or merged in a tax-free basis with another high-end networks and defense company which could generate substantial synergies from the combination.

Starboard also believes that the Issuer is a highly strategic asset for a number of well-capitalized companies in the RF and semiconductor markets, and to the extent that an alternative acquisition or merger proposal emerges, Starboard reserves its rights to evaluate any such alternative proposal in relation to the announced RFMD merger.

CUSIP NO. 89674K103

Starboard continues to have discussions with the board of directors of the Issuer (the “Board”) regarding Starboard’s director nominations and believes that the addition of at least one new individual to the board of directors of NewCo would be in the best interests of the Issuer’s Board and shareholders.

Due to the recent stock price appreciation of the Issuer’s Shares, Starboard has reduced the size of its position in the Issuer as part of its regular portfolio management activities.
