Design of an S-Band Mircostrip Synthesizer
Cheng Shi-xu · Telecommunication Engineering · 2008
S-band and X-band are adopted in transmission signal of deep space exploration in order to ensure high reliability and low attenuation of signal.To realize high power combiner for SSPA(state solid power amplifier),an S-band eight-way mircostrip synthesizer is designed.Simulation with ADS(Advanced Design System) shows that the in-band transmission coefficient is 9 dB,reflection coefficient 35 dB,isolation coefficient 30 dB,respectively.
