How do I develop a matlab program for the conversion of S-parameter to Z-parameter from results of measurements of a saw resonator using a VNA?

I have taken measurements of the reflection coefficients of a saw resonator using a Vector Network Analyser. Now I want to develop a matlab program to convert the S-parameters to Z-parameter(S11 to Z11).

hi zeinab.

you should save your data from vna as s2p file(touchstone file). you can use matlab to open this file. just type this in the matlab help:Reading and Analyzing RF Data from a Touchstone Data File

What is saw resonator?

Convert your S-parm file to Z-parm and plot impedance plots..you can use below fucntion to do that.

Z = zparameters('defaultbandpass.s2p');

z11 = rfparam(Z,1,1);

plot(Z.Frequencies, imag(z11)) ;% this is for imaginary part of Z-, change as per your requrements

look below link for more info..

does anyone know how to use X-parameters in MATLAB/SIMULINK?

These are power dependant S-parameters that simulators or test equpment produce.
