y2s

Convert Y-parameters to S-parameters

Syntax

s_params = y2s(y_params,z0)

Description

s_params = y2s(y_params,z0) converts the admittance parameters y_params into the scattering parameters s_params. The y_params input is a complex N-by-N-by-M array, representing M N-port Y-parameters. z0 is the reference impedance. The default value of is z0 50 ohms. s_params is a complex N-by-N-by-M array, representing M N-port S-parameters.

Examples

collapse all

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 to s-parameters

s_params = y2s(y_params)
s_params = 2×2 complex

   0.0038 + 0.0248i   0.9961 - 0.0250i
   0.9964 - 0.0254i   0.0037 + 0.0249i
