RF and IF port isolation in Cadence Spectre

friends,
I'm implementing a mixer using cadence spectre, I want to know about the analysis what we can do in spectre for mixer's RF and IF port isolation, i.e. how to get final result.
Another question I have, which analysis we can do in spectre to know the voltage/power gain of that RF mixer, same as we are doing s-parameter simulation in ADS?
Can anyone say the step by step procedure?
regards

Please forget this, I found it irrelevant lately. Marking it as Solved.
