rfdata.noise class

Package: rfdata

Store frequency-dependent spot noise data for amplifiers or mixers

Syntax

h = rfdata.noise
h = rfdata.noise('Freq',value1,'FMIN',value2,'GAMMAOPT', value3,'RN',value4)

Description

Use the noise class to store spot noise specifications for a circuit object.

h = rfdata.noise returns a data object for the frequency-dependent spot noise, h, whose properties all have their default values.

h = rfdata.noise('Freq',value1,'FMIN',value2,'GAMMAOPT', value3,'RN',value4) returns a data object for the frequency-dependent spot noise, h, based on the specified properties.

Properties

FMINMinimum noise figure data

RNEquivalent normalized noise resistance data

Examples

f = [2.08 2.10]*1.0e9;
fmin = [12.08 13.40];
gopt = [0.2484-1.2102j 1.0999-0.9295j];
rn = [0.26 0.45];

noisedata = rfdata.noise('Freq',f,'FMIN',fmin,...
                         'GAMMAOPT',gopt,'RN',rn);
