s2z
Convert S-parameters to Z-parameters
Description
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 S-parameters to Z-parameters.
z_params = s2z(s_params,z0)
z_params = 2×2 complex

Input Arguments
s_params
— N-port- S-Parameters
N-by-N
M array of complex numbers
N-port- S-Parameters, specified as an N-by-N M array of complex numbers, where M represents the number of frequency points of N-port S-parameters.
z0
— Reference impedance
50
(default) | positive real scalar | vector
Reference impedance of an N-port S-parameters, specified as a positive real scalar in ohms.
Note
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.
Output Arguments
z_params
— N-port Z-parameters
N-by-N-by-M array of
complex numbers
N-port Z-parameters, returned as an N-by-N-by-M array of complex numbers, where M represents the number of frequency points of N-port Z-parameters.
