| Abstract(in English) | In this paper, we present a solid state power amplifier (SSPA) for Ku-band applications. This is the first report of SSPA using with gallium nitride (GaN) field effect transistors (FETs), which output power exceeds 50W as world commercial record for Ku-band. We apply a linearization technique to GaN FETs' power amplifiers for the purpose of improving a linearity of RF module. The intermodulation distortion is under -25dBc with 50dBm output power at -10C to +45C. The SSPA controls RF gain stability with a temperature compensator for FETs which connected with 12 steps straightly. |
