Abstract :
The development of broad-band microwave amplifiers using state-of-the-art GaAs power FET´s covering the 6-12-GHz frequency band is presented. A unique circuit topology incorporating an edge-coupled transmission line section for both impedance matching and input/output dc blocking is described. The microstrip circuit design of an X-band 1-W 22-dB-gain GaAs FET amplifier is also discussed. Microwave performance characteristics such as intermodulation, AM-to-PM conversion, and noise figure are included.
