ADS simulation help - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 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 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. 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 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

Hello 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.
