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
