Front end simulation

Hello,

I am trying to simulate the front-end, which includes LNA, mixer, OSCILLATOR and LO buffer. Just wonder whether it is possible to get the gain, NF and IIP3 using PSS/PAC/Pnoise.
The spectreRF manual has the example using a port/vsin for the LO, but if the port is replaced with an LC oscillator, how to set it up ?

Thanks
