Dear ACWWONG,
Yes, I mean the one in rfLib/balun in Cadence. This balun allows me to set the impedance of balance and unbalance ports. However, the TF3 in ADS does not provide this setting to me. It just allows me to set the number of turn in primary and secondary coil. I have tried to add a series 50ohms resistor in the TF3 and simulate the s-paramter. It does not give me a 50ohms matching. However, it is correct in the rfLib/balun in Cadence as I set the correct impedance in rfLib/balun setting. If I wanted the TF3 with same impedance, how could I do?
Thanks
