# Harmonic balance and ADS! - RF Cafe Forums

 RF Cafe Forums closed its virtual doors in 2010 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. 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. NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board. -- Antennas -- Systems

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?

Hello,

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,
