Computer-Aided Design of Hybrid FET Amplifiers Above 20 GHz.
29 May 1987
We describe the CAD of hybrid FET amplifiers and report on the performance of a specific amplifier from 36-40 GHz. The measured gain of 6 dB at the band center was approximately 1 dB higher than that predicted by the CAD program. The gain compression at an output power of 20 mW was 1 dB and the corresponding power added efficiency was 20%. The circuits can be adapted to frequencies up to 60 GHz.
