Hi

I want to simulate wire bonds that can convert 50 ohm to 25 ohm, my laser driver is 50 ohm differential and my modulators end at 25 ohm, I need impedance matching through them, how should I go about this? I tried simulating them through an example online, but my pub structure is different so hence need to create a new one. I need sweep of length vs impedance of the wire along with the S parameters. 
if someone has any idea about it please let me know.

You can use lumped port and set the port impedence in its property window.

Would using wave ports be okay, to get reflections and parasitic inductances also?
