I was trying to simulate a down
converter using ansoft designer. apparently there is no mixer block
in designer. can someone pl guide me on how to create the netlist for
the mixer or, is there a mixer library that i can use?

did u try including all the libs. if not in
the tools menu configure libs .. add all the libraries. are you using
the complete version or the student version?

I am assuming
you are looking at the student version. If that is the case, note from
the readme file:
o Only linear circuit simulation is supported
in Ansoft Designer SV.
You cannot simulate non-linear devices. You
can, however, insert
non-linear devices into your circuits and transfer
to the professional version of Ansoft Designer.
If you can locate an older student version of Ansoft Serenade v8.5,
you can simulate non-linear effects with some limitations. I still use
Serenade v8.5 as I don't like Designer much and the limitations are

1. i was trying to use the
circuit simulation package in ansoft designer. now i am using the system
simulation part and i was able to locate the mixer. i am now trying
to run temperature sweeps on my circuit. when i use the inbuilt temp
sweep in ansoft, nothing seems to happen to the S parameters. I plugged
in a couple of manufacturer datasets for different temperatures and
got totally different results, compared to the temp sweep in ansoft.
does anyone have an explanation??
2. I was wondering about how
to determine the S-parameters of the mixer. I wanted to use custom defined
S parameters for the mixer in my simulation. How do i determine S12,
S21, S31, S32 & S23/32??
3. In Ansoft Designer, how do I
import a touchstone file for a bandpass filter? I was able to import
the s2p file for the amplifier, but the BPF properties dialog doesnt
seem to have an option to import an s2p file..
