摘要
本文通过对矢量网络分析仪中射频接收机电路原理的分析,介绍了串扰信号对提高矢量网络分析仪动态范围的重要性,讨论了矢量网络分析仪中三种主要串扰信号的产生,给出了如何通过电路设计消除相关的串扰信号,提高射频接收机的隔离。
Through the analyzing to vector network analyzer of radio receiver circuit philosophy, we introduced the importance of cr osstalk signal to improve vector network analyzer dynamic range, and discussed how the three main crosstalk signals causing in vector n etwork analyzer. Then we proposed method to remove the interrelated crosstalk signals by using circuit design, and improved the radio r eceiver' s isolation.
