A Study on Worst-Case Analysis of 2-Stage Amplifier in Ku-Band SSPA for Communication Satellite

위성채용 Ku-Band SSPA를 위한 2-단 증폭기의 Worst-Cast Analysis에 관한 연구

In this paper, We designed a 2-stage amplifier for transponder of satellite with dual GaAs FETs NE13783, and performed the worst-case analysis for circuit qualification in the space environment. The bandwidth of amplifier was chosen 11.7-12.2 GHz which is the down link frequency band for domestic Ku-band satellite communication, and the alumina substrate with 25 mil of thickness. The design and optimization of amplifier was achieved by the commercial CAD program TOUCHSTONE and the measurement was performed through the automatic network analyzer.
