Harmonic balance and 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.

Hi, I am a girl who has 2 questions for you. What is harmonic balance? And is it possible to make ADS to work with Matlab?

Harmonic Balance is a method to solve non-linear circuits. The circuit is being analyzed according to Kirchoff's law by injecting N tones to it. The currents and voltages are then being calculated for each tone. This method can be implemented for active devices only if they are provided with their Spice model, since this model allows non-linear analysis.

Harmonic Balance lets you find out various parameters as: IP3, P1dB etc.

Regarding ADS and Matlab, as far as I know they can't be working together.

ADS works with Matlab well in ptolemy simulation environment.

Ptolemy can be a top-level simulation co-simulating with circuit envelope and matlab. Do you want both HB and matlab in the same simulation ?
There are different ways of doing things in ADS. Sometimes, it may also be possible to save the results of one simulation in a file(sink type=file) and then use that file as a source in 2nd simulation.

Good luck,
