abcd2z

Convert ABCD-parameters to Z-parameters

Syntax

z_params = abcd2z(abcd_params)

Description

z_params = abcd2z(abcd_params) converts the ABCD-parameters abcd_params into the impedance parameters z_params. The abcd_params input is a complex 2N-by-2N-by-M array, representing M 2N-port ABCD-parameters. The function assumes that the ABCD-parameter matrices have distinct A, B, C, and D submatrices:

z_params is a complex 2N-by-2N-by-M array, representing M 2N-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 ABCD-parameters to Z-parameters:

%Define a matrix of ABCD-parameters.
A =      0.999884396265344 +  0.000129274757618717i;
B =      0.314079483671772 +      2.51935878310427i;
C = -6.56176712108866e-007 + 6.67455405306704e-006i;
D =      0.999806365547959 +  0.000247230611054075i;
abcd_params = [A,B; C,D];
%Convert to Z-parameters
z_params = abcd2z(abcd_params);
