Analysis of Passive Intermodulation Distortion of Ku-Band Payload System for Communication & Broadcasting Satellite

This paper describe the passive intermodulation products(PIMs) which are formed in high power Ku-band transponder and antenna subsystem on the Communication St Broadcasting Satellite(CBS)program when two transmit carriers beat together to generate harmonics that fall into the receive band. How the PIMs are initially generated and the effect of PIMs for Ku-Band payload system are analyzed by calculating the PIMs frequencies and the power level of PIMs.
