I'm trying to match the following network using the Matching Network Designer so that the resistance curves (solid lines) get pulled towards the horizontal

line and the reactance curves (dotted lines) get pulled towards the

line.

I was wondering if there was any way to do this using the matching network designer like this:

MyMatchingNetwork = matchingnetwork("SourceImpedance",50,'LoadImpedance',330+4000i,'CenterFrequency',14.2e6);

% Dispay circuits generated

[circuit_list, performance] = circuitDescriptions(MyMatchingNetwork);

% Now plot the frequency response of the best circuit (cuicuit #1)

% between 7-50MHz

freqs = linspace(7e6,50e6,100);

This seems to work for creating a circuit that will match a source to load over a single center frequency. I want to create a circuit that will match the network in the figure over several bands (as indicated by the vertical lines) where the load impedance is different at each band.

If someone could point me in the right direction on how to do this in MATLAB I would be most grateful,

Kind regards,

Adrian.
