如何测试混频器的隔离度呀

学习中。

用sp分析 看s参数

There is no way to simulate the isolations of mixers, unless the manufactur provides the multi-ports S paramaters or other kinds of models. The only way to get these numbers are runing the measurements according to your specific application conditions.

用pss+psp，把LO端看成输入port，信号输入端看成输出port，看S21即是隔离度
