• Released 1x2 PA for 802.11n applications to high volume production

Commenting on the results for the quarter ended June 30, 2008, Ralph Quinsey, President and Chief Executive Officer, stated “TriQuint is on track for achieving our product development and design win targets for the year with each of our markets generating strong order activity and a strong book to bill ratio of 1.29. Multi-band and multi-mode applications are accelerating RF demand with two to four times the content for TriQuint products in new applications. I expect the second half of 2008 to be a solid growth period for TriQuint.”

Summary Financial Results for the Quarter Ended June 30, 2008:

Revenues for the second quarter of 2008 were $127.0 million, including $5.6 million from WJ Communications, and were up 12% from the second quarter of 2007 and 14% sequentially. Strong growth in wireless LAN and 3G handset products led the way in the quarter.

Net income for the second quarter of 2008 was $3.4 million, or $0.02 per diluted share, down from $4.5 million or $0.03 per diluted share in the prior quarter. Excluding all WJ Communications’ results, net income in the second quarter was $5.0 million or $0.03 per diluted share. Please see below for TriQuint and WJ Communications’ results that are reconciled to the consolidated results of the Company. Non-GAAP net income for the second quarter was $9.6 million or $0.07 per diluted share. Non-GAAP financial measures exclude stock based compensation charges and certain charges associated with the acquisition of WJ Communications. Please see the attached supplemental schedule for a reconciliation of GAAP to non-GAAP financial measures.

Gross margin for the second quarter of 2008 was 34.6%, flat with the prior quarter. Excluding WJ Communications, gross margin was 35.1%. On a non-GAAP basis, gross margin was 37.0%, up from a non-GAAP gross margin of 35.5% in the prior quarter. Improving product yields and the higher margins of the WJ Communications products drove the increase.

Operating expenses for the second quarter of 2008 were $41.8 million, or 33.0% of revenue, up from $35.8 million in the first quarter. Excluding WJ Communications, operating expenses totaled $39.0 million. Non-GAAP operating expenses were $38.7 million or 30.5% of revenue. In the latter half of this year, we expect non-GAAP operating expenses to converge with our operating model of 25% of revenue. However, inclusion of the higher margins and operating expenses associated with the WJ Communications business may cause us to make slight adjustments to our business model targets.

Cash, cash equivalents and short-term investments were $98.3 million as of June 30, 2008, a decrease of $121.0 million from March 31, 2008. Cash was consumed by the purchase of WJ Communications, substantial capacity investments and growth in inventory in preparation for rapid growth in the coming quarter. In addition, approximately $17.6 million was invested in long term investments with maturities greater than a year.

Outlook:

We estimate that third quarter 2008 revenue will be $155 million to $170 million. Third quarter earnings are expected to range between $0.06 and $0.08 per diluted share. We expect non-GAAP earnings to range between $0.10 and $0.12 per diluted share. As of today, we are approximately 95% booked for the third quarter.
