Global Communication Semiconductors, Inc. (GCS) Announces High Linearity HFET Foundry Process for Wireless Infrastructure Amplifier Applications

GCS, Inc. (Global Communication Semiconductors, Inc.) a pure-play III-V compound semiconductor wafer foundry announced today that its proprietary high performance Heterostructure FET (HFET) process will now be offered to address the high dynamic range requirement of base station driver amplifiers.

"GCS has a number of proprietary FET technologies including 0.5um and 0.25um PHEMT processes. Our 0.5um high performance HFET process is the latest addition to the FET family. With a breakdown voltage of 16V with a pinch off voltage of -2.0V, this technology was developed specifically with high linearity in mind and it is ideal for linear amplifiers that require high dynamic range," commented Jerry Curtis, Chief Executive Officer of GCS. "As a performance example at 2.0 GHz, when biased at 8V and 50% Idss, our 1.2mm HFET device can achieve an output power of 28.1 dBm with a Third Order Intercept (TOI) point of 48.5 dBm. With a 20.4 dB linear figure of merit, a difference between TOI and P1dB, our HFET is by far one of the most linear foundry processes ever available. Similar linear performance can also be achieved at 5.0V bias. The superior linearity makes it well suited for use in both analog and digital wireless communication infrastructure and subscriber equipment including 3G, cellular, PCS and fixed wireless system," continued Mr. Curtis.

Global Communication Semiconductors Inc., based in Torrance, California, an ISO 9001-2000 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 various components such as PIN PD, PIN POD Array, APD, VCSEL and lasers used in the fiber optic communication market.
