RF PDK for Cadence Virtuoso 6.1

Hi guys,

I am going to do a project related to using Cadence Virtuoso to design a RF transmission circuit. However I dont have any RF PDK at the moment. The version I am using is Cadence 6.1 . Any suggestion where I can find PDK for that, I did ask my teacher but still waiting from him. I went through some RF CMOS design tutorials, they were using Cadence 5.1 and the library they used was PRIMLIBRF, but i couldnt find that either. Thanks
