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...

GaAs MESFET SPICE Model - 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'm trying to simulate a circuit on ADS that works between
500MHz and 2500MHz. I decided to use a GaAs MESFET but I'm having some
problems in finding an accurate model. Can anyone point me to where
I can get accurate models (some examples of devices that I would like
to find SPICE models for are CLY5, CLY10, or CLY15)? If these models
are not available, how can I know the values to input in the MESFET
model in ADS?

There are ususally 2 sources for that:
1. To ask the manufacturer
for the SPICE model.
2. The data is available in the ADS or other
simulation tool you are using.
Sometimes the SPICE model is
not available as a file but as a list of parameters which you have to
manually enter into the simulation tool. I have done that several times
in the past with GaAs FET transistors which I used for design an RF
If you need more information, please
let me know.

also in ADS a feature
called netlist translator , u can convert the models of pspice , hspice
, spectre to ADS model , it is very efficient
