ansoft designer simulation help - RF Cafe Forums
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.

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?

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 these circuits
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..
