无源互调测量面临的问题

Problems of Passive Intermodulation Measurement

随着移动通信更大功率发射的应用以及接收灵敏度的不断提高,无源互调产生的系统干扰日益严重。由于无源互调干扰难于准确进行理论建模分析,因此,测量是对无源互调干扰进行预测和控制的重要方法。为此,本文介绍了目前无源互调测量所面临的挑战,从4个方面进行了详细分析,以期为无源互调测量系统的设计提供参考。

With the application of higher power transmission in mobile communication and the lower requirement of receiving sensitivity, the system interference caused by passive intermodulation becomes more and more serious. Due to the difficulty of theoretical modeling and analysis of passive intermodulation interference, measurement is an important method to predict and control passive intermodulation interference. Therefore, this paper introduces the challenges faced by passive intermodulation measurement at present, and makes a detailed analysis from four aspects, in order to provide reference for the design of passive intermodulation measurement system.
