WJ to Showcase Its Latest Products at MTT-S 2005; Long Beach Convention Center -- Long Beach, CA, June 14-16, 2005.

SAN JOSE, Calif. -- WJ Communications, Inc. (Nasdaq:WJCI), a leading supplier of RF solutions for the wireless infrastructure and RFID reader markets, today announced that it will showcase its newest products at the upcoming 2005 IEEE MTT-S International Microwave Symposium (IMS) and Exhibition. IMS2005 will be held at the Long Beach Convention Center in Long Beach, CA, between June 14th-16th, 2005. The ECM168 10V power amplifier module, AP series 12V power amplifier modules, MH103A and MH203A high linearity mixers, MPR5000 and MPR6000 RFID reader modules, and a variety of other WJ RFICs will be on display in the company's exhibit, booth #1827. WJ will also provide a demonstration of the AP501 and AP502 12V power amps, highlighting their exceptional ACLR performance. In addition, WJ will be presenting at the Practical Implementation of RF Power Amplifiers for Cellular Base Stations workshop, on Sunday, June 12th, from 1:00 p.m. - 5:00 p.m. WJ's presentation will be given by Larry Wang, vice president of power amplifier development for WJ Communications, and will focus on High-Voltage HBT's for Cellular Base Station PAs.

"WJ is committed to maintaining its position as a leading RF semiconductor company," said Ron Buswell, senior vice president of marketing and product line management for WJ Communications. "The addition of the 10V and 12V power amplifier modules is an example of our continued innovation to meet our worldwide customers' demands to provide complete solutions for base station transmit and receive chain applications and to expand our addressable markets."

New Semiconductor Products

10V Power Amplifier Module -- ECM168

The ECM168 is a 1.9GHz power amplifier module utilizing InGaP HBT process technology optimized for PHS/PAS applications. Key features include; 33.5dBm output power, a single 10V supply, 33dB typical gain and excellent ACPR2 @ 600kHz offset. No negative voltage is required and the efficiency is in excess of 20%. The ECM168 is housed in a low cost, flange mount package measuring only 29 x 13 x 4 mm.

12V Power Amplifier Modules -- AP Series

The AP series are high linearity InGaP HBT power amplifier modules optimized for driver or final stage amplifier mobile infrastructure applications. These devices are multi-stage, and are internally optimized for efficiency and linearity. Each PA module in the family features 50 ohm operation including internal matching for input and output and operates off +12 V without requiring negative biasing voltages. Additionally, an internal active bias allows the devices to maintain high linearity over temperature. The AP's have the added feature of a +5 V power down control pin. A low-cost 29 x 13 x 4 mm metal housing with bolt-down flange allows these devices to have a low thermal resistance, and these amplifiers achieve over 100 years MTTF. All devices are 100% RF and DC tested.

High Linearity Mixers -- MH103A and MH203A

Among the key benefits of the MH103A and MH203A are high IP3, up to +34 dBm, and low conversion loss. The MH103A and MH203A are passive GaAs MESFET mixers that provide high dynamic range performance in a low cost SOIC-8 package. These devices use patented techniques to realize +34 dBm Input IP3 at an LO drive level of +17 dBm when used in transceiver applications as an up-converter or a down-converter. These single monolithic integrated circuits do not require any external baluns or bias elements. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in 3G UMTS systems.

Price and Availability

Catalogs, data CD's and samples can be obtained and requested by visiting WJ's booth #1827 at IMS2005 or via an online request form (www.wj.com). All devices are available for sampling now. Samples and production pricing information can also be requested directly from the WJ website.
