How to design a filter in MATLAB using the data from an S2P touchstone file

sparameters

Create S-parameter object
Syntax
hs = sparameters(filename)example
hs = sparameters(hnet)example
hs = sparameters(data,freq)
hs = sparameters(__,Z0)
hs = sparameters(cktobj,freq,Z0)example
Description
example
hs = sparameters([COLOR="#40E0D0"]filename[/COLOR]) creates an S-parameter object hs by importing data from the Touchstone file specified by filename.

example
hs = sparameters([COLOR="#40E0D0"]hnet[/COLOR]) creates an S-parameter object from the RF Toolbox network parameter object hnet.

hs = sparameters([COLOR="#40E0D0"]data,freq[/COLOR]) creates an S-parameter object from the S-parameter data, data, and frequencies, freq.

hs = sparameters(__,[COLOR="#40E0D0"]Z0[/COLOR]) creates an S-parameter with reference impedance of Z0.

example
hs = sparameters([COLOR="#40E0D0"]cktobj,freq,Z0[/COLOR]) calculates the S-parameters of a circuit object.

Examples

Extract and Plot the S-parameters of a File
Extract S-parameters from file default.s2p and plot it.

S = sparameters([COLOR="#EE82EE"]'default.s2p'[/COLOR]);
disp(S)
rfplot(S)
