GCS offers a total of six (6) power processes (P1, P2, P3, P5, P6, and P7) for handset wireless, WLAN, mobile WiMAX and infrastructure markets.
Our P1 and P2 processes are designed to achieve high ruggedness and superior linearity at the same time. The P5 process features unbreakable ruggedness and high power efficiency at the same time was designed for GSM/EDGE power amplifier application. Several customers (including IDMs) have reported excellent VSWR >15:1 with 5V Vcc bias.
GCS also offers two digital processes (D1 and D5), providing high fT, very low phase noise, integrated varactor and Schottky diodes, ideal for applications such as VCO, tunable filters, and high speed ICs.
