4-ports differential S parameters to Z parameters

Dear all,

It is quite messy in my head !
I am trying to reconnect S-parameters to Z-parameters; for a 2 ports system, it is quite easy.
But for a 4 ports system, I must admit I am not so confident !

Do you have some ressources talking about this kind of task?

Thanks a lot for your help

Regards

This page might help.

Good luck.

Hi Baas Rietrot,

Unfortunately, this page's about 2-ports matrices...

N-port matrix conversions is discussed first, above 15.1 down to 15.9 (Loads of N by N matrix conversions). Then the 2-port transformations (N=2).
