3 ports s parameters balun cadence

Hi, i have a problem i don't really know how to measure s-parameters in a 4-port network. Do i use a balun to convert into a 2 port network o what should i do?.

This is the 4-port network i was reffering to.

4 port s parameter network

You can do that with spectreRF. PDF somwhere there doc/spectreRF/spectreRF.pdf. At first you have to do PSS analysis and then the one everything to do with s-param (I forgot how is it called)
 

convert s-parameter from cadence to ads

Drive the network differentially and you ended up with 2 ports.
 

how to convert 2 port s-parameter to 4

But what happen with the values of s31 ... and s41 ...
