Hello,
I am using ADS 2015. I have created a differential channel.Now I want to do TDR simulation. I googled and found schematic settings below.
In the settings after step in the input 100 ohm and 25 ohm are put and similar to the output ports as well. I want to know why is 100 ohm and 25 ohm are attached? why not 50 ohm & 50 ohm?
Is there any other way to do TDR simulation for differential channel except TDR frontpanel tool?
Have you noticed the balun element in this schematic? At the differential port, we then have a 50 Ohm + 50 Ohm = 100 Ohm, at the common mode port we have 50 Ohm || 50 Ohm = 25 Ohm.
