PRESS RELEASE

TRIQUINT UPDATES GUIDANCE

FOR FOURTH QUARTER 2008 RESULTS

HILLSBORO, OREGON, USA – December 16, 2008 - TriQuint Semiconductor, Inc. (Nasdaq: TQNT) updated its guidance today for the quarter ended December 31, 2008. Significant order push-outs and a drop in new orders have reduced our anticipated revenue to a range of $140 million to $145 million, down from our previous estimate of $160 million to $175 million. At the new range midpoint projected for Q4, revenue for 2008 will be approximately 19% above revenue for 2007.

With TriQuint’s market capitalization well below book value, we are examining the potential impairment of our goodwill and currently expect to write off the full balance of $34.2 million. We are also examining the potential impairment of a cost based investment in a privately held company and currently expect an impairment charge of approximately $2 million.

Based on results to date and projections for the remainder of the quarter, GAAP loss is expected to range between 20 to 22 cents per share. Excluding the unusual items above, GAAP earnings are expected to be between 2 and 4 cents per share and non-GAAP earnings will range between 5 and 7 cents per share. We expect strong positive cash flow during the quarter.

TriQuint has taken significant cost control measures including a sharp reduction in temporary employees, closure of most open staffing requisitions, restrictions on discretionary spending and planned shutdowns over the holiday period. At the same time, we are continuing to invest in innovative new products, technologies and more efficient processes. We believe TriQuint remains well-positioned financially and strategically heading into 2009, with ample cash reserves, continued market share gains, and a strong technical roadmap.

Non-GAAP Financial Measures:

This press release provides financial measures for net income and diluted earnings per share that exclude equity compensation expense, the charges associated with the acquisition of WJ Communications and impairment charges and are therefore not calculated in accordance with accounting principles generally accepted in the United States (“GAAP”). Management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance that enhances management’s and investors’ ability to evaluate TriQuint’s operating results.
