I fabricated a few microstrip transmission lines on the PCB, and I got the S-parameter measurement data (s2p files) on these lines using a vector network analyzer. Now I'm trying to extract the R, L, G, C values of the transmission line from these s2p data files. Is it possible to do the extraction in MATLAB. Are there any MATLAB codes I can find to do this job?
first convert s-paramerters to ABCD parameters and then from ABCD parametes and the follwing equations you can extract Zc and gamma and then RLGC parameters.
gamma=arccosh(A)/L L is the length of TL
Zc= sqrt(B/C)
I can send you 2 small mfile for converting s-parameters to RLGC parameters, if you want.
I've done some simulation and I need some experimental s-parameters to compar wirh my results. Can I have your results, please?
here you go!
Length = 3.6cm
Width = 2.5mm
Height = 1.4 mil
Er (dielectric constant) = 2.2
The material is made by Rogers Corp, DT/Duroid 5870/5880 series.
If you're able to use ADS, there is a tool to extract or to find an equivalent circuit ( Broadband or Narrowband Model Generator) that consist of RLCG elements from some sort of circuit parameters including s-parameters and z-parameters etc..
