Using s2rlgc for 4 port network

The documentation page for s2rlgc command defines the s_params input: "2N-by-2N-by-M array of S-parameters to transform into RLGC transmission line parameters." This implies that s_params can be a 2x2 or 4x4, etc... I have used a 4x4 and it gives the following error code: Cannot compute RLGC matrix for given data. It works for a 2x2, but why is it not working for 4x4?

Hi Derek,

As per my understanding of the question, you can break up your parameters into a 2-port system and then apply the function separately for the same.

You can refer the documentation for the example.

Convert S-parameters to RLGC transmission line parameters - MATLAB s2rlgc (mathworks.com)

I hope this resolves your query.
