uW_S2H

Scattering parameter matrix to Hybrid matrix convertion for 2 ports matrix.

Calling Sequence

H=uW_S2H(S)

Parameters

S

tlist containing the S parameters.

H

tlist containing the H parameters calculated from the S parameters.

Description

This function convert a S parameter object into a H parameter one. It works only for 2 ports devices (S2P).

Examples

filename="transistor.s2p";
S=uW_S2P_read(filename);

// === Trace for ft
subplot(211);
H=uW_S2H(S);
plot2d(H.frequency,20*log10(abs(H.H21)),logflag="ln")
a=gca();
a.x_label.text="Frequency(Hz)";
a.y_label.text="H21(dB)";

// === Trace for Fmax
subplot(212);
M=abs(S.S21)./abs(S.S12);
plot2d(H.frequency,10*log10(abs(M)),logflag="ln")
a=gca();
a.x_label.text="Frequency(Hz)";
a.y_label.text="MSG(dB)";
