Convert S-parameters to Y-parameters


y_params = s2y(s_params,z0)


y_params = s2y(s_params,z0) converts the scattering parameters s_params into the admittance parameters y_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. y_params is a complex N-by-N-by-M array, representing M N-port Y-parameters.


z0 can be a positive real scalar or vector. If z0 is a vector, then the vector must be equal to the number of network parameter data points.

Define the s-parameters and impedance.

s_11 = 0.61*exp(1i*165/180*pi);
s_21 = 3.72*exp(1i*59/180*pi);
s_12 = 0.05*exp(1i*42/180*pi);
s_22 = 0.45*exp(1i*(-48/180)*pi);
s_params = [s_11 s_12; s_21 s_22];
z0 = 50;

Convert the s-parameters to y-parameters.

y_params = s2y(s_params,z0)
y_params = 2×2 complex
