摘要
介绍了卫星无源互调(PIM)的产生机理、抑制方法,讨论了天线、同轴电缆和射频连接器等部件的无源互调控制技术,以及无源互调的测量方法。针对风云二号卫星转发通道提出了一种无源互调测试方法,测试结果表明可发现PIM。
The cause and mitigation of passive inter-modulation （PIM） in satellite were introduced in this paper. The PIM mitigation techniques of the antenna, coaxial cable and radio frequency junction were discussed. A PIM measurement method for the transponder tunnel of FY-2 satellite was put forward. The test results showed that the PIM could be measured.
