Abstract: Based on array application of GaN power amplifier module, a 4-channel X-band 50 W power amplifier module is designed using GaN power monoliths and gate modulation. In the frequency band of 8-12 GHz, with the operating voltage of +28 V, a pulse width of 200 ns-700 μs and a pulse period of 1 μs-2.8 ms, the power gain is more than 42 dB, the power additive efficiency exceeds 28.7%, and the saturated output power is more than 47 dBm。

Key words: power amplifier module, GaN, gate, X-band, 50 W
