摘要
对移动通信天线的无源互调干扰问题进行了探讨与分析。介绍了天线系统中的无源非线性及其产生原因,对移动通信天线无源互调的测量进行了一定的探讨,给出了天线PIM测量的典型装置;结合测量实例检验了测量装置的实用性;最后提出了移动通信天线中PIM产物的减小措施。
This paper discusses passive intermodulation interference in mobile communication antennas.It introduces the passive nonlinear and its causes in antenna system.At the same time,this paper studies the measurements of mobile communication,provides the typical device measured antenna PIM,and tests the practicality of the measuring devices along with examples,Finally,this paper puts forward the ways of reducing PIM products in mobile communications antenna.
