BEND, Ore.--(BUSINESS WIRE)--June 3, 2002

Advanced Power Technology, Inc. (Nasdaq:APTI), a leading supplier of high performance power semiconductors used in the conditioning and control of electrical power is announcing, on the occasion of the Microwave Theory and Technique Symposium (MTT-S), held in Seattle, Washington from June 4 to June 6, the formation of Advanced Power Technology RF (APT-RF).

This newly formed organization and brand is the result of the integration of the RF businesses of APT and of two recent RF acquisitions, GHz Technology, Inc. (January 2002), and Microsemi RF Products (May 2002).

The mission of APT-RF is to be the world leader in non-Cellular/PCS high power silicon RF & microwave power transistors. To this end, APT-RF will expand VDMOS products for broader coverage of HF and VHF ISM and communication applications, expand LDMOS offerings into non-cellular/PCS CW and pulsed applications for VHF, UHF, and microwave, and continue to offer leading edge bipolar performance in HF, VHF, UHF, avionics, L-band and S-band applications for frequencies up to 3.5 gigahertz.

On a proforma basis for the prior four quarters ending March 31, 2002 APT-RF revenues represented 47% of the APT total revenues. "I believe the combined RF & microwave talents of APT-RF make us the technology leader in the markets we serve. Capitalizing on these combined talents, we intend to intoduce a strong flow of new products, continuously pushing the performance envelop and providing our customer with a winning combination of performance and cost." said Frank W. Schneider, vice president and chief operating officer of APT-RF.

With operations in Bend, Oregon, Santa Clara, California, Montgomeryville, Pennsylvania and Bordeaux, France, APT is a leading supplier of high voltage, high power MOSFETs, IGBTs, Bipolar Transistors, Ultra-Fast Recovery and Schottky Diodes, and Application Specific Power Modules (ASPM(R)) for RF, Linear, and Switch Mode applications.
