Hello, I have simulated a situation where we have 3 differential lines as shown below.
port 1 has no termination so he has to affter SDD23 .
From sdd23 we se resonances spaces 1.23GHz one from another.
substrate er=4.1
the traxes are 50mm long.
How can I link the distance between the resonance and the agressor of port 1 trace length?
Thanks.
