TRIQUINT SEMICONDUCTOR, INC. UPDATES GUIDANCE

FOR SECOND QUARTER 2007 RESULTS

Hillsboro, Oregon – July 17, 2007 – TriQuint Semiconductor, Inc. (Nasdaq: TQNT), a supplier of high performance products for communications applications, today updated its guidance for the quarter ended June 30, 2007. Although the results for the second quarter of 2007 quarter are not finalized, preliminary results indicate that revenue will be in the range of $113 million to $114 million, in line with previous guidance. Net income is expected to be in the range of $1 million to $2 million or approximately $0.01 per diluted share, a decline from previous guidance of net income of approximately $6 million or earnings per diluted share of $0.05.

Excluding equity compensation expense of approximately $2 million, net income is expected to be in the range of $3 million to $4 million or $0.02 to $0.03 per diluted share.

The primary reason for the unexpected change in forecasted net income is a charge of approximately $4 million for inventory that unexpectedly became excess, largely due to a reduction in demand from a significant customer. Guidance for the full year ending December 31, 2007 is now for revenue to increase 14%-18% over 2006 and for earnings growth of 10% - 20%.
