RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

ADS simulation help - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

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