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.

Input Arguments

collapse all

N-port- S-Parameters, specified as anN-by-N-by-Marray of a complex numbers, whereMrepresents the number of frequency points ofN-port S-parameters.

Reference impedance ofN-port S-parameters, specified in positive real scalar as ohms.

Note

z0must be a positive real scalar or vector. Ifz0is a vector, then the vector must be equal to the number of network parameter data points or frequency vector.

Output Arguments
