TRIQUINT SEMICONDUCTOR, INC. ANNOUNCES FIRST QUARTER REVENUE GROWTH

Hillsboro, Oregon – April 25, 2006 – TriQuint Semiconductor, Inc. (Nasdaq: TQNT), a supplier of high performance products for communications applications, today reported its financial results for the quarter ended March 31, 2006.

Summary Financial Results and Highlights for the Quarter Ended March 31, 2006:

• Revenues from continuing operations for the first quarter ended March 31, 2006, totaled $87.9 million, an increase of 31% from the first quarter of 2005 and an increase of 4% from the previous quarter.

• Net income for the first quarter of 2006 was $2.2 million including equity compensation expense of $2.3 million. Earnings for the first quarter of 2006 were $0.02 per diluted share. Our results for the quarter ended March 31, 2006, reflect the effect of the adoption of Statement of Financial Accounting Standards (“SFAS”) No. 123(R), which became effective for our company on January 1, 2006. Excluding our SFAS No. 123(R) expense of $2.3 million, our earnings for the quarter ended March 31, 2006, improved to $0.03 per diluted share.

• Gross margin for the quarter ended March 31, 2006, equaled 30.3%, including equity compensation expense, and 31.1%, without equity compensation expense, up 2.4% from gross margin of 28.7% in the fourth quarter of 2005. This increase was primarily due to yield improvements.

• Operating expenses for the first quarter of 2006 were $25.4 million including equity compensation expense of $1.5 million. Excluding equity compensation expense, our operating expenses for the first quarter of 2006 were $23.9 million, an increase of $2.2 million from the fourth quarter of 2005. The

- more -

increase was due to increases in research and development spending of $1.8 million and sales, general and administrative spending of $0.4 million.

• Cash, cash equivalents and short and long term marketable securities were $392.0 million as of March 31, 2006, compared to $406.7 million as of December 31, 2005. Cash flow from operations for the first quarter of 2006 was $1.6 million. During the quarter we repurchased $4.7 million of stock, made a $3.8 million payment related to our 2005 acquisition of TFR Technologies, Inc., and acquired $10.4 million in capital assets. Depreciation and amortization expense was $8.0 million. EBITDA was $9.2 million and pro forma EBITDA, excluding equity compensation expense was $11.5 million.

• We continued our strong bookings during the quarter with a book-to-bill ratio of 1.2 to 1.0 for the quarter ended March 31, 2006.

Commenting on the results for the quarter ended March 31, 2006, Ralph Quinsey, President and CEO, stated, “In the first quarter of 2006, we reached the high end of our revenue guidance and exceeded our earnings guidance. The favorable results validate our progress towards our long term goals of innovation, profitable growth and market share gains in our target markets. Due to our new product success our revenue outlook for 2006 is improving. I am also pleased to report that we have received the Preferred Supplier Platinum Award from Lockheed Martin. This prestigious award is made only to Lockheed Martin suppliers who distinguish themselves by meeting some of the most stringent performance criteria in the aerospace industry. We are honored to be a recipient.”

Outlook for the Second Quarter of 2006:

Revenues for the second quarter of 2006 are expected to increase 8% to 10% from the first quarter of 2006 due to increased sales of wireless phones and broadband products. Gross margin is expected to improve due to increased capacity utilization and yields partially offset by increased operating expenses. We are projecting earnings per share for the second quarter of 2006 to range from $0.01 to $0.02 per diluted share including equity compensation expense of approximately $2.6 million. Excluding equity compensation expense charges associated with SFAS No. 123(R), we are projecting earnings of $0.03 to $0.04 per diluted share.

Outlook for 2006:

Revenues for 2006 are expected to increase 34% to 37% over 2005 revenues. Earnings per share for 2006 including equity compensation expense are expected to be $0.08 to $0.13 and $0.16 to $0.20 excluding equity compensation expense.

TriQuint will host a conference call this afternoon at 2:00 p.m. PDT to discuss the results for the quarter as well as our future expectations for the Company. The call can be heard via webcast accessed through the “Investors” section of TriQuint’s web site: www.triquint.com, or through www.Vcall.com.
