High-Voltage FET Amplifiers for Satellite and Phased-Array Applications

The high-voltage FET amplifier (HVFA) configuration for power amplifier applications in satellite communications and phased-array systems can offer substantial improvement in DC-to-RF conversion efficiency. A proof-of-concept experiment, design considerations, and the RF results of MIC implementation at C- and X-band are reported. An X-band MMIC HVFA design is also presented.
