| Abstract: | With the rapid develop of large antenna technology in satellite communication, transmitter-receiver sharing technology has been widely used in satellites.Passive intermodulation(PIM) in high and low temperature environment has become focus of attention.At present,the simulation and calculation methods are limited to solve the problem of temperature influences to PIM performance from the design perspective.In order to improve the reliability of in-orbit antenna performance.It is an effect measure to test the PIM in high and low temperature environment.In this paper, two systems of testing PIM in high and low temperature environment are researched and developed.At the same time,the test results are given about this systems applied in practical engineering .The test system fully meet the verification requirements of ground test. |
