| How do I do this in ADS? - RF Cafe Forums | ||||||
|
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
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. Qacer Post subject: How do I do this in ADS?

I saw an example using HP MDS. The example consisted of one BJT with the port 1 (base) and port 2 (collector) terminated with a variable termination block that had variable resistance and reactance parameters (p. 443 on Gonzalez's Micowave Transistor Amplifiers book). How can I replicate this on ADS? ADS has a termination block for the S-param simulation, but I don't know how to set it so I can set the source and load impedance into variables. The idea is that when the simulator is given specific goals it would return the value for source and load impedances that meet those goals. I can do this easily by coming up with an arbitrary input and output matching network. However, I don't know how to get ADS, just to give me the optimum values, so I can come up with my own matching network configuration. Thanks!

It is a fairly simple solution. The termination block under the S-param palette has internal variables. If you actually double click on it after placing it on the design space, then you'll see "Equation Editor" in the pop-up window. By clicking on "Equation Editor" you will see the list of variables associated with the termination block: source_real, source_imag, etc.. Posted 11/12/2012 | ||||||
