Using ADS Library in Genesys?

Hi all, I want to simulate a power amplifier using NXP RF power transistor in Genesys. However, the NXP website only provides me with the ADS model (library) for its specific product that I want to use.
Can I somehow use this ADS model in Genesys? My version is 2009. I tried to open the NXP library from Genesys, but it requires different extension file (Genesys requires .xml file while the NXP's ADS library doesn't have any xml file)
I appreciate your help. THanks...
