TRIQUINT to acquire the Gallium Arsenide semiconductor business of INFINEON

HILLSBORO, OREGON and MUNICH, GERMANY April 29, 2002 – TriQuint Semiconductor, Inc., (Nasdaq/FSE: TQNT) and Infineon Technologies AG, Munich (FSE/NYSE: IFX) today announced that the two companies will partner and join forces to revolutionize radio designs for wireless phones and devices. The two companies entered into a partnership to develop and produce highly integrated radio frequency, RF, components and modules for customized wireless system solutions.

An initial step of this cooperation is the acquisition of Infineon’s gallium arsenide, (GaAs), semiconductor business by TriQuint Semiconductor, Inc with a scheduled acquisition closing on July 1, 2002, subject to regulatory approval and customary closing conditions. The transaction includes development and marketing activities with approximately 80 former Infineon employees. In the fiscal year ending September 30, 2001, Infineon’s GaAs activities had a total revenue of approximately $35 million.

Through the cooperation with TriQuint Semiconductor Inc., a leading supplier in this market, Infineon strengthens the market position of its GaAs product portfolio for customized solutions and assures an improved cost position and economy of scale.

For TriQuint, this partnership provides access to Infineon’s technologies and system solution platform, and will strengthen its European presence. TriQuint will not acquire the manufacturing operations, but rather enter into an interim supply agreement with Infineon while the process is being transferred to TriQuint’s Oregon operation. Infineon’s GaAs business will report to TriQuint’s Wireless Modules and Worldwide Sales business unit.

Jointly, both companies will benefit through this cooperation by concentrating resources to provide more cost effective, higher integrated, higher performance front-end RF solutions for future wireless phones and devices.

“This transfer of our GaAs products and capabilities in combination with our cooperation roadmap positions us as the leading player in the radio solution technology, a key component for future mobile wireless devices” says Ulrich Hamann, CEO of Wireless Solutions Business Group at Infineon Technologies. “We are pleased to have TriQuint as a partner.”

Steven J. Sharp, Chairman, President and CEO of TriQuint, stated “This partnership with Infineon gives TriQuint access to Infineon’s broad product technology, its customers, a strong European presence, approximately 80 highly skilled employees, and access to the Infineon wireless systems house architecture for future wireless phones. We believe that this is the beginning of a highly successful cooperation with an outstanding partner.”
