GaAs FET power amplifiers for PCS applications

For wireless base station applications, high linearity GaAs FET amplifiers have been developed. The PCS family of amplifiers offers premium performance over the 1.9 to 2 GHz frequency range and at power levels from 5 to 200 W. The PCS 1900 family of high power amplifiers have achieved the required code division multiple access (CDMA) performance by using a high linearity class A GaAs FET design.
