Abstract

There is a trend to replace TWTA of SSPA in S-Band uplink application for satellite operation. KARI developed l20W full S-Band SSPA system in early 2004. This paper covers SSPA system design and its test results. Through tests, nominal gain of 57dB, gain stability of +/-1dB over frequency, and gain stability of +/-0.5dB over temperature were shown. IMD value of -16.5dBc, -19dBc were revealed in PI and P3 output operations. With meeting specifications, l20W SSPA is expected to be used in operational S-Band uplink application.
