TORRANCE, Calif.--(BUSINESS WIRE)--April 21, 2003

GCS, Inc. (Global Communications Semiconductor, Inc.), a pure-play III-V compound semiconductor wafer foundry, announced today that its proprietary High Performance InGaP HBT process, currently in high volume production, will now be offered to address the demanding requirements of 802.11a/b/g power amplifiers required in WLAN products.

"GCS has a number of proprietary InGaP HBT processes. Our P2 process was developed specifically for 802.11 power amplifiers. This process provides a better breakdown voltage and has a self-limiting current feature that prevents total burnout," commented Dr. Sam Lee, Chief Executive Officer of GCS.

"This process gives a competitive edge to our customers addressing the rapid growth WLAN market. It has long been recognized that GaAs (Gallium Arsenide) based power amplifiers and particularly InGaP HBT designs are exceptionally suited for the more demanding linearity requirements of 802.11a and 802.11g WLAN standards. GCS' P2 process distinguishes itself a notch above the competition with better gain, linearity and lower dc power consumption as compared to SiGe and other GaAs based technologies. The power consumption of Power Amplifier Modules utilizing the P2 process has been reduced by 30% allowing for significantly longer battery life that is crucial for laptop and other portable WLAN applications. In addition, our cost structure allows us to compete successfully for the high volume markets, where we are currently shipping in a high volume WLAN product program," continued Dr. Lee.

Global Communication Semiconductors Inc., based in Torrance, Calif., an ISO 9001-2000 certified company, provides compound semiconductor foundry services to the wireless telecommunication and high-speed networking industries. GCS currently offers foundry services for InGaP HBT, InP HBT and PHEMT processes and provides optoelectronic foundry services for QWIP detectors, modulators & PIN diodes used in the surveillance, security and fiber optic communication markets.
