Advanced Power Technology RF (APT-RF) Introduces P-Band Higher Power, High Gain, Medium Pulse Transistors; Expansion of P-Band Line Verifies Commitment To The Future of Radar Markets.

SANTA CLARA, Calif. -- Advanced Power Technology RF's Military & Aerospace Division (APT-RF) (Nasdaq:APTI), a leading supplier of silicon power transistors for radio frequency (RF) and microwave applications, is pleased to announce a new product family of high power transistors targeting for the P-Band Pulsed Radar Applications. These new products utilize newer chip designs and processing enhancements to offer state-of-the-art performance, notably in high power and high gain over the frequency range and the lowest droop over 150us pulse width.

The P-Band series transistors consists of three model types: 0910-60M, 0910-150M, and 0910- 300M, which cover the frequency for P-Band Radar Applications from 890 to 1000 MHz with a pulsed output power of 60W, 150W, and 300W, respectively. These transistors are designed to handle medium pulse widths of 150us with a duty cycle of 5% minimum. The high performance class C 300W device, for example, offers unparalleled performance of 9.6 dB of power gain, 50% collector efficiency and extremely low droop, 0.5 dB or less, across the 150 us pulse width. This state-of-the-art performance is achieved with the latest APT RF's Si BJT high power technology.

0910-300M Key Features:

--Designed for P-Band Radar Application: 890 - 1000 Mhz

--Able to Handle Medium Pulse Format:150 us, 5%

--Excellent Output Power:300W

--Outstanding Power Gain:9.6 dB

--Superb Droop Performance:0.5 dB

--Rise Time:150 ns

--Collector Efficiency:50%

--Compression:In Compression

--Load Mismatch:VSWR 3:1

--Package:Hermetic Metal Package

By integrating 4, 6, or 8 of the 0910-300M transistors with a 0910-150M and 0910-60 as the driver and pre-driver stage; customers can comfortably achieve kilowatts output power for P-Band Radar application.

"We are extremely pleased to offer these top-notched P-band products, in addition to the existing APT RF L-Band Radar Product Family. These latest P-Band products extend the frequency coverage available to our valued Radar customers," said Jerry Chang, Director of Radar and RF Module Business. "Radar customers turn to APT-RF for our strong custom design and development capability, excellent technical and product support, and ability to deliver high volume transistors that provides the best repeatability and consistency in the industry."
