Abstract—In this work, a design of X-band solid-state power amplifier (SSPA) is proposed. Its operating frequency is from 7.7 GHz to 8.5 GHz, and the matching circuit is designed as a band-pass filter circuit. The results show that the power added efficiency of the single-stage power amplifier designed by GaN HEMT can reach 55%, the saturated output power is 51.5 dBm, and the maximum power gain can reach about 12 dB.
