z2abcd

Convert Z-parameters to ABCD-parameters

Syntax

abcd_params = z2abcd(z_params)

Description

abcd_params = z2abcd(z_params) converts the Z-parameters to ABCD-parameters.

Examples

Convert Z-Parameters to ABCD-Parameters

Define a matrix of Z-parameters.

Z11 = -14567.2412789287 - 148373.315116592i;
Z12 = -14588.1106171651 - 148388.583516562i;
Z21 = -14528.0522132692 - 148350.705757767i;
Z22 = -14548.5996561832 - 148363.457002006i;
z_params = [Z11,Z12; Z21,Z22];

Convert Z-parameters to ABCD-parameters.

abcd_params = z2abcd(z_params)

abcd_params = 2×2 complex

   1.0002 - 0.0002i   0.3151 + 2.5200i
  -0.0000 + 0.0000i   1.0001 - 0.0001i

Input Arguments

z_params — 2N-port Z-parameters

2N-by-2N-by-M array of complex numbers

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

Output 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-parameters matrices have distinct A, B, C, and D submatrices:

$$\left[\begin{array}{cc}[A]& [B]\\ [C]& [D]\end{array}\right]$$
