Simulate TWS/RWS 434a in Proteus

Hi all

I am working on a project which involves the use of 89s52, an RF module (TWS/RWS 434a) and a few more bits and pieces but I desire to simulate the circuit in Proteus first, before i actually go ahead and make a real one. This part is not available in Proteus Lib. So I have looked everywhere, from the Proteus Parts Lib. to Spanish forums. However, I have not been able to find it. I did read on a thread on eda itself that I have the option to download a simulation which already includes this rf module and save the required parts to my library in Proteus. However, the link for that is dead now and I am stuck. Can anyone help me in adding this part to my Proteus lib. or maybe even building one if that is what it has to all come down to?

Many Thanks

P.S. I have one of those red ones and not the green one, if that makes any difference.

Integrated Circuits can not be simulated except certain primitive devices.
Why you would simulate it ? It's a module, connect the power supply,outputs,inputs,other stuffs and use it ..There is nothing to simulate..
