S11：端口2匹配时，端口1的反射系数；S22：端口1匹配时，端口2的反射系数；S12：端口1匹配时，端口2到端口1的反向传输系数；S21：端口2匹配时，端口1到端口2的正向传输系数；
•回波损耗(ReturnLoss):入射功率/反射功率,为dB数值反射系数(Г):反射电压/入射电压,为标量电压驻波比(VoltageStandingWaveRation):波腹电压/波节电压S参数:S12为反向传播系数，也就是隔离。S21为正向传播系数，也就是增益。S11为输入反射系数，也就是输入回波损耗，S22为输出反射系数，也就是输出回波损耗。• 四...

回波损耗，反射系数，电压驻波比,S11这几个参数在射频微波应用中经常会碰到,他们各自的含义如下:•回波损耗(ReturnLoss):入射功率/反射功率,为dB数值反射系数(Г):反射电压/入射电压,为标量电压驻波比(VoltageStandingWaveRation):波腹电压/波节电压S参数:S12为反向传输系数，也就是隔离。S21为正向传输系数，也就是...
1、回波损耗回波损耗(Return Loss)Return Loss,简称回损或RL,又称为反射损耗。是指信号在电缆中传输时被反射回来的信号能量强度。 当高频信号在电缆及通信设备中传输时,遇到波阻抗不均匀点时,就会对信号形成反射,这种反射不但导致信号的传输损耗增大,并且会使传输信号畸变,对传输性能影响很大。这种由信号反射引起的衰减...
