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 S-parameters to Z-parameters.

Input Arguments

collapse all

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

Reference impedance of anN-port S-parameters, specified as a positive real scalar in ohms.

Note

z0can be a positive real scalar or vector. Ifz0is a vector, then the vector must be equal to the number of network parameter data points.

Output Arguments

collapse all

N-port Z-parameters, returned as anN-by-N-by-Marray of complex numbers, whereMrepresents the number of frequency points ofN-port Z-parameters.
