WebApr 11, 2024 · Zin = 50* (1 + S11)/ (1 - S11) And. Zout = 50* (1 + S22)/ (1 - S22) where Zin and Zout are the impedances looking INTO the device. You have to mutiply by 50 to convert the normalized impedance into ohms (assuming your S parameters were measured on a 50 ohm network analyzer). The table you published has S11 as mag [s11] and ang [s11] for … WebDefine S-Parameters. RF Toolbox™ software uses matrix notation to specify S-parameters. The indices of an S-parameter matrix correspond to the port numbers of the network that the data represent. For example, to define a matrix of 50-ohm, 2-port S-parameters, type: s11 = 0.61*exp (j*165/180*pi); s21 = 3.72*exp (j*59/180*pi); s12 = 0.05*exp (j ...

WebDec 22, 2024 · In two-port S-parameters, S21 and S12 are insertion loss or transmission parameters, and they should be approximately the same. S11 and S22 are the return loss or reflection parameters. These can be unique if the device is not symmetrical. These are typically plotted in voltage dB.
