y2abcd

Convert Y-parameters to ABCD-parameters

Syntax

abcd_params = y2abcd(y_params)

Description

abcd_params = y2abcd(y_params) converts Y-parameters to ABCD-parameters.

Examples

Convert Y-Parameters to ABCD-Parameters

Define a matrix of Y-parameters.

Y11 =  0.0488133074245012 - 0.390764155450191i;
Y12 = -0.0488588365420561 + 0.390719345880018i;
Y21 = -0.0487261119282660 + 0.390851884427087i;
Y22 =  0.0487710062903760 - 0.390800401433241i;
y_params = [Y11,Y12; Y21,Y22];

Convert Y-parameters to ABCD-parameters.

abcd_params = y2abcd(y_params)

abcd_params = 2×2 complex

   0.9999 + 0.0001i   0.3141 + 2.5194i
  -0.0000 + 0.0000i   0.9998 + 0.0002i

Input Arguments

y_params — 2N-port Y-Parameters

2N-by-2N-by-M array

2N-port Y-Parameters, specified as an 2N-by-2N-by-M array, where M represents the number of frequency points of 2N-port Y-parameters.

Output Arguments

abcd_params — 2N-port- ABCD-parameters

complex 2N-by-2N-by-M array

2N-port- ABCD-parameters, specified as a complex 2N-by-2N-by-M array, 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:

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