Abstract :
An 8 GHz, 10 W GaAs FET prototype power amplifier has been developed to replace the TWT in the Northern Telecom´s digital microwave radio system. For a single bit stream of 91.04 Mbit/s, the residual bit error rate at 40 dBm output level was 1.0×10¿32 compared with 1.0×10¿23 for TWT; the AM/AM conversion ratio was 0.375 dB/dB and AM/PM was 0.84°/dB. The total mean time between failure of the amplifier was 350 000 h.
