Generic 2.5-W 60% Bandwidth C-Band MMIC Amplifier (MSAG)

This paper reports the design and test data of a generic 2.5-W two-stage C-band MMIC power amplifier developed using the MSAG® MESFET process. We measured typically a minimum PAE of 45% and 2.5W CW output power over the 4.5 to 7.4 GHz for the MMIC chip packaged on CuW carrier. The output power and PAE for ceramic packaged chips were reduced by about 0.5 dB and 3% points, respectively.
