SANTA CLARA, Calif.--(BUSINESS WIRE)--Feb. 22, 2000

Celeritek, Inc. (Nasdaq:CLTK) announced today the May availability of two new 50 Ohm matched, 6mm square, power amplifier modules for 2.5G and 3G high bandwidth WCDMA wireless data markets.

Celeritek's new InGaP HBT amplifier modules are part of the TrueTriangle(TM) product line offering 50% size reduction to comparable solutions. They are specifically targeted to maximize linear efficiency for challenging wireless data applications.

"Both the CHP0230-PM and CHP2230-PM WCDMA power modules give handset designers unique compact solutions for 2.5G and 3G applications. They offer the linear efficiency needed for high speed data in WCDMA environments. As the GSM world moves towards wider bandwidth, WCDMA solutions (such as the CHP2230-PM) could address a portion of the 200 million GSM subscriber market -- expected to grow to 500 million by 2002. The CHP0230-PM addresses nearer term 1X WCDMA opportunities like IMT-2000," said Bill Hoppin, Vice President of Semiconductor Sales and Marketing.

Model CHP0230-PM is a 824 to 849 MHz, multi-mode, 2-stage, power amplifier solution for 1X cellular handsets and wireless local loop (WLL) subscriber units. It offers 40% linear power added efficiency, 60% analog power added efficiency, with +28.5 dBm output power (1X WCDMA mode).

Model CHP2230-PM is a linear efficient, 3-stage, 1920 to 1980 MHz, power amplifier developed for WCDMA 3G cellular handsets and infrastructure systems. It offers 30% linear power added efficiency at 28 dBm under 3X WCDMA modulation.

Common features include operation as low as 3.2 volts from a single positive supply, and 30 dB gain at operating output power. Measuring only 6 mm square x 1.7 mm high they both provide excellent electrical stability and low thermal resistance. Reduced circuit board space and cost is further achieved due to minimum matching elements (eliminating as many as 14 external elements) and no negative supply. This significantly reduces valuable circuit board space by as much as 1/2 that of currently available solutions.

Data Sheets of the amplifiers contain specifications, applications, circuit design considerations, recommended application schematic as well as ordering information. Samples of both amplifiers will be available in May, 2000, in bulk and in tape-and-reel. Celeritek's complete in-house manufacturing capability guarantees quality and reliability in each step of the production process. Volume quantities are priced at $6.00 per unit for model CHP0230-PM and $7.10 per unit for model CHP2230-PM. Please e-mail direct product inquiries for TrueTriangle(TM) HBT modules to: [e-mail].
