s2z

Convert S-parameters to Z-parameters

Syntax

z_params = s2z(s_params,z0)

Description

z_params = s2z(s_params,z0) converts the scattering parameters s_params into the impedance parameters z_params. The s_params input is a complex N-by-N-by-M array, representing M N-port S-parameters. z0 is the reference impedance; its default is 50 ohms. z_params is a complex N-by-N-by-M array, representing M N-port Z-parameters.

Alternatives

You can also use network parameter objects to perform network parameter conversions. For more information, see RF Network Parameter Objects.

Examples

Convert S-parameters to Z-parameters:

%Define a matrix of S-parameters
s_11 = 0.61*exp(j*165/180*pi);
s_21 = 3.72*exp(j*59/180*pi);
s_12 = 0.05*exp(j*42/180*pi);
s_22 = 0.45*exp(j*(-48/180)*pi);
s_params = [s_11 s_12; s_21 s_22];
z0 = 50;
%Convert to Z-parameters
z_params = s2z(s_params,z0)
