Oct 03, 2005 11:09 am Hi,
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?

Nov 08, 2005 1:32 pm 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?

Guest Post subject: Posted: Tue Nov 08, 2005 3:04 pm 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
these circuits 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
more severe.

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..
