Measurement for microstrip balun without ground reference

Dear all,

We have a microstrip balun but without ground reference for differential outputs. How can we design a test scheme for measurement of such kind of balun? Thanks a lot.

You can use Balun4Port (Balun, 4-port) in ADS

Hi, it may not work for my case...

I want to design a test scheme for our microstrip balun without ground reference on PCB board...

Anybody could help me? Thanks a lot.
