Design of a 25W C-Band Power Amplifier for Satellite Communication

This paper presents the design methodology of a highly efficient 25W C-band power amplifier in hybrid technology using Gallium Nitride device. The proposed amplifier is designed and developed for prospective use in the telemetry application of satellite communication. Over a frequency range of 3.95 GHz to 4.35 GHz, the measured output power is more than 43.9 dBm which is well matching with the simulation results. Measured drain efficiency and linear gain are around 65% and 11.5 dB, respectively in the desired frequency range.
