Convert ABCD-Parameters to Y-Parameters

Open Live Script

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 ABCD-parameters to Y-parameters.

y_params = abcd2y(abcd_params)

y_params = 2×2 complex

   0.0488 - 0.3908i  -0.0489 + 0.3907i
  -0.0487 + 0.3909i   0.0488 - 0.3908i

Input Arguments

`abcd_params` — 2N-port- ABCD-Parameters
2N-by-2N-by-M array of complex numbers

2N-port- ABCD-Parameters, specified as a 2N-by-2N-by-M array of complex numbers, where M represents the number of frequency points of 2N-port ABCD-parameters.

The function assumes that the ABCD-parameter matrices have distinct A, B, C, and D submatrices:

$[\begin{matrix} [A] & [B] \\ [C] & [D] \end{matrix}]$

`y_params` — 2N-port Y-Parameters
2N-by-2N-by-M array of complex numbers

2N-port Y-Parameters, returned as a 2N-by-2N-by-M array of complex numbers, where M represents the number of frequency points of 2 N-port Y-parameters.
