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
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Harmonic Balance simulation

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?
