High Linearity InGaP HBT (P2) processes with high ruggedness at the same time have been developed specifically for battery-powered high linearity power amplifier applications. High Linearity Power Amplifiers with superior performance and reliability have been demonstrated by customers for Infrastructure gain blocks, CDMA/WCDMA/TD-SCDMA, WiFi and WiMAX. Both processes have been in mass production since 2001.
