Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all

Hello, I need help with ADS. I'm a beginner….
I want to simulate
isolation between 2 cables. Each cable is represented as RLC circuit.
I'd like to inject sine wave into Port 1
and measure the signal at the adjacent cable.
How can I do it?
S-Parameter simulation? How?
Or maybe AC
simulation, name both ports Vin and Vout and use an equation?
Thanks in advance. Andrei

To my understanding you can´t simulate
isolation in the way you described. You will need to use a distributed model of coupled lines. There are several
models available in ADS according ot the number of coupled lines and this is located under the TL library. To do
that you have to model your cable as a distributed line, based on this model you can also define the distance
between the lines and calculate the isolation (Coupling) between them. You can do it with linear (S-parameter)
simulation and terminate to the unused ports.
Hope it helps.
