SAN JOSE, Calif.--(BUSINESS WIRE)--June 3, 2004

WJ Communications, Inc (Nasdaq:WJCI), a leading designer and supplier of high-performance RF semiconductors and multi-chip modules, today announced that it will showcase its newest products at the 2004 IEEE MTT-S International Microwave Symposium (IMS) and Exhibition. IMS2004 will be held at the Fort Worth Convention Center in Fort Worth, TX, between June 6-11, 2004. The AG103 general gain block amplifier, the SX2000 and SX2030 RFID reader engines, the AH118 HBT driver amplifier, the AG606 push-pull amplifier for CATV applications, and a variety of other WJ RFICs will be on display in the company's exhibit, booth #2135.

"WJ continues to expand its product lines and grow into new markets, offering OEM's a wide variety of RF solutions for their wireless, CATV, RFID, and defense applications," stated Javed Patel, senior vice president of sales and marketing at WJ Communications. "The IMS and Exhibition is a longstanding forum for the wireless systems component market and an important showcase for our new semiconductor products."

New Semiconductor Products

High Dynamic Range Gain Block -- The AG103 uses WJ's highly reliable GaAs MMIC process and only requires DC-blocking and bypass capacitors, and an inductive RF choke for operation. The AG103 general-purpose gain block offers good dynamic range and low noise figure in a low-cost surface-mount package. The combination of high OIP3 and a tight gain variation window makes it attractive for a multitude of applications. The device combines dependable performance with high quality to maintain MTTF values exceeding 1000 years at mounting temperatures of +85 degrees C and is housed in a SOT-89 industry-standard SMT package. The AG103 is well suited for wireless infrastructure such as NMT-40, homeland security, and 2nd generation mobile infrastructure utilizing the cellular band, and in addition the amplifier can be used for applications in various IF frequency bands.

RFID Reader Engines -- WJ recently released two RF reader engine products for RFID applications. The SX2000 is an Auto-ID Center Class 1 EPC compliant reader operating in the 900 MHz ISM band. The SX2030 operates in the worldwide 2.4 GHz band. Each model in WJ's family of compact reader/programmer engines reads and programs EPC Class 1 RFID tags. The SX2000 and SX2030 full performance, low-cost and small size -- roughly the size of a PCMCIA card -- enables the realization of a wide range of portable and hand-held reader/programmer solutions including integrated RFID/barcode readers.

InGaP HBT Amplifier -- The low-cost AH118 is targeted for use as a driver amplifier in wireless infrastructure applications where high linearity and medium power are required. The AH118 operates across a broad frequency range from 60-2500 MHz and provides +41 dBm OIP3 and +24 dBm of P1dB power. It is housed in an industry-standard SOT-89 SMT package. This device is ideally suited as a final stage amplifier for repeaters, mobile infrastructure transceivers, CATV/DBS, RFID and defense applications.

Push-Pull CATV Amplifier -- The AG606 is a dual amplifier containing two internally matched and optimized amplifiers for a push-pull configuration. The internal amplifiers employ InGaP HBT technology for a cost-effective low-distortion solution. The AG606 operates over a broadband frequency range of 50-860 MHz and features excellent 2nd order performance of +68 dBm OIP2 while providing excellent VSWR when used in a push-pull, 75ohm configuration and is housed in an industry-standard SOIC-8 package. The AG606 is ideal for drop amplifiers, splitters, and other low to moderate power outside plant CATV applications. The device can also be used in CATV trunk amplifier and medium-power headend applications such as linear laser drivers.
