I am trying to design a bluetooth balun. I tried to achieve it in ADS. But I can't make the s-parameter right. I used the tuning tool in ADS. I changed all the variables, and I found that the input return loss and the output return loss conflicted with each other. According to the Marchand theory, it shouldn't happen. I am wondering why. Could you help me? Thanks very much in advance.
Here is a picture of my circuit:
And I also attached the circuit.
