Global Communication Semiconductors, Inc. (GCS) Announces Low Cost 0.5um PHEMT Switch Foundry Process for GSM Switch Application

GCS, Inc. (Global Communication Semiconductors, Inc.), a pure-play III-V compound semiconductor wafer foundry, announced today that its proprietary low cost PHEMT switch process will now be offered to address the high linearity and compact size requirements of SP6T switches for GSM cell phone applications.

"Our low cost 0.5um PHEMT switch process was developed specifically for GSM cell phone applications with high linearity performance in mind. This process provides a breakdown voltage of 20V with a pinch off voltage of -1.0V. It has been used to design GSM SP6T switches to handle input powers of up to 4 watts with second and third harmonics lower than -80 dBc," commented Dr. Sam Lee, Chief Executive Officer of GCS. "Besides having an excellent linearity performance, our switch process also exhibits low insertion loss and high isolation characteristics. A typical insertion loss of 0.3 dB with isolation of greater than 20 dB can be obtained from a GSM SP6T switch measured at 900 MHz.

"The excellent performance allows our customers to design a variety of switches in today's cost competitive market. During the past years, several of our strategic customers, with access to our pre-announced process, have already designed switch products in SP2T, SP3T, SP4T and SP6T configurations. All of them have demonstrated excellent results. Several of these switch products are now in volume production with electrical yield of greater than 98%. This low cost PHEMT Switch process gives a competitive edge to our foundry customers in addressing different switch requirements in today's price competitive environment," continued Dr. Lee.

Global Communication Semiconductors Inc., based in Torrance, California, an ISO 9002 certified company, provides compound semiconductor foundry services to the wireless telecommunication and high-speed networking industries. GCS currently offers foundry service for InGaP and InP HBT, Power and switch PHEMT processes and provides optoelectronic foundry services for PIN diodes and lasers used in the fiber optic communication market.
