RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

ansoft designer simulation help - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

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..
