WebJun 13, 2012 · A colleage and I are having a discussion about the meaning of the scattering parameters S12 and S21. My belief is that if the system is perfectly matched (S11=S22=0), then the ratio of the signals at port 1 to port 2 are given by S21. So if the input to port 1 is 1 V, the output from port 2 is 10 V, then S21 is 10. Webs22：端口1匹配时，端口2的反射系数（输出回波损耗）； s12：端口1匹配时，端口2到端口1的反向传输系数（隔离）； s21：端口2匹配时，端 … cemcolift repair https://enco-net.net
