Abstract :
A 4 GHz high power FET amplifier for digital transmission is presented. The four-stage amplifier is composed of six amplifier-modules, and has 3 W output with 25 dB gain in linear operation and 6 W output with 22 dB at saturation over the 3.7-4.2 GHz range. In 45 Mbit/sec 8-PSK signal transmission, this amplifier shows approximately 0.1 dB degradation in C/N.
