MICs based on pseudomorphic HEMTs (pHEMTs) have been in volume production at Raytheon Microelectronics for several years. Applications include low-noise and power amplifiers from UHF through millimeter-wave. The largest single application for pHEMT technology is in power amplifiers for cellular and personal communication system mobile handsets. These power amplifiers presently operate in the voltage ranges of 3 to 7.5 volts depending on the generation of the platform. CDMA and TDMA
