The Key Techniques to Design a Ku-band Communication Satellite Simulate Transponder

Weiwei Ma

Abstract

A transponder is the communication subsystem of a communication satellite.As the special equipment for the communication satellite transponder's ground testing,simulate transponders are mainly used for simulating the relations of transponder's frequency and level.The structure and characteristics of the transponder are introduced in this paper.The simulate transponder's key techniques such as NF,gain distribute,and EMC characteristics are analyzed in detail.A scheme adopting the simple frequency conversion system to implement a sort of simulate transponder is provided.Test result proves the feasibility and reliability of the design.
