Serving the RFIC/MMIC industry, GCS offers a wide portfolio of process technologies such as InGaP HBT, InP HBT, pHEMT, HFET, GaN HEMT, THz Mixer Diode and Integrated Passive Devices (IPD) to enhance our customers’ product performance and market competitiveness. A family of InGaP HBT processes are in production, each tailored to provide an optimum performance (high power and superior linearity) for a unique application in the cellular handset, wireless communication and base station markets.
Several GaAs HEMT foundry processes are also in production for applications from low cost handset switches, PAs and LNA up to 40GHz, to high linearity an high power PAs. GaN-on-Silicon process for high power RF PAs is also qualified for production.
