(Gilbert cell). When I run Harmonic Balance simulation everything
is ok 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 mixer. The problem is that when LO=RF the simulator returns some
rubbish results or nothing at all. I tried that on Agilent ADS and
Microwave Office. Any idea what I am doing wrong? Is it some kind
of limitation of the Harmonic Balance Simulation? How to overcome
this problem? Thanks, Przemek Top Profile

9:48 am 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?
