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...

Harmonic Balance simulation - 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.

I need to sumulate a mixer
When I run Harmonic Balance simulation everything
if I put different LO and RF frequencies.
In my design I
use LO=RF and I am interested in the DC
component / performance of
The problem is that when LO=RF the simulator returns some
results or nothing at all. I tried that on Agilent ADS and
Any idea what I am doing wrong? Is it some kind
of limitation of the Harmonic Balance Simulation?
How to overcome

Assuming that tthe model you are using is OK ( non linear
model), then you can try and increase the number of harmonics of the
simulator, although this may not help since the expected output should
be a DC signal with perhaps leakage tones from the RF and LO ports.
Is the simulator giving you a convergence error?
