PIM interference testing methods of satellite communication components and setting up of the testing system

摘要

The PIM(passive intermodulation) interference testing methods of satellite communication components was discussed in this article. According requirements and characteristics of satellite communication components, main indexes of signal separation devices were given to design a PIM interference testing system. Based on indexes and low PIM crafts and technologies, main devices were produced and the testing system was setting up. After calibration the system achieved the goal of design with an experiment.
