gammaml

Load reflection coefficient of 2-port network

Syntax

coefficient = gammaml(s_params)
coefficient = gammaml(hs)

Description

coefficient = gammaml(s_params) calculates the load reflection coefficient of a 2-port network required for simultaneous conjugate match.

s_params is a complex 2-by-2-by-M array, representing M 2-port S-parameters, Sij. coefficient is an M-element complex vector.

coefficient = gammaml(hs) calculates the load reflection coefficient of the 2-port network represented by the S-parameter object hs.

Examples

collapse all

Calculate the load reflection coefficient using network data from a file

ckt = read(rfckt.amplifier,'default.s2p');
s_params = ckt.NetworkData.Data;
coefficient = gammaml(s_params);

Algorithms

The function calculates coefficient using the equation

ΓML=B2±B224|C22|2C2

where

B2=1|S112|+|S222||Δ2|C2=S22ΔS11*Δ=S11S22S12S21

Introduced in R2008a
