摘要：

根据二极管特性,分析了无源互调的产生机理,讨论了无源互调对移动通信的影响。理论分析表明,我国的GSM900存在三阶交调,严重影响接收机性能。文中以天线为例给出了有效的无源互调测试方案,实际测试结果表明,该方案能准确测量对小功率交调信号。

Abstract:

The impact of non-linear passive components intermodulation products caused by the quality of communication is serous.Based on the diode characteristics,the mechanism of passive intermodulation is analyzed.The effect of passive intermodulation in mobile communications is discussed.Theoretical analysis shows that intermodulation in GSM900 system can decrease the performance of receivers.In order to accurately measure the intermodulation products,an effective passive intermodulation test programs is presented,which can accurately measure the low power quantity of intermodulation.
