I have simulated two rings in CST and I have S2P file exported to ADS

If I have s2p files using two lumped ports, how to connect this s2p file to a balun in ADS giving that these lumped ports are actually differential ports.

Shall I connect one of the balun outputs to ground and the second to s2p and balun's input is connected to a terminal ? and reference s2p to ground as well ?
 

Hi,

A Balun is actually a 4-port network, so you need to export the s4p file from CST and connect is deferentially in ADS.

Hi Romansh,

Thanks a lot for your reply, however, when I used discrete port for a single antenna it will export S1P and if I have two antennas, CST will export S2P so it does not tell if it is a differential port

The balun I am using is actually a 3-port network, so I was thinking how to connect this balun to a S2P file
 

Can you please provide a sketch of the CST and ADS simulation setup

If you Balun has 3ports, you will evidently use S3P block in ADS in order to it simulate.
S3P can be found in the same palette of S2P.
 

Dear all, if I want to connect the S2P file that has two ports with one Balun for each port, is it right way to connect with a reference for each port or connect both to a single reference in S2P
