ADS - Mixer Simulation

I'm using ADS for designing a mixer in 3-4.8 Ghz. I have draw the circuit schematics. But I don't know how I should simulate it with ADS.

I'm new to ADS. So, I need specific steps just for simulating a mixer. I need all the simulations required for typical mixer characteristics like Gain, NF, IP3, Power. Anyone can give a guide on where to start? or tell me any settings that are required?

Use "Mixer Design Guide" in ADS.It will bring you a ready to use test-bench to simulate your mixer.
All you should do to change the sample circuit with yours..
Choose the appropriate test-bench and play with simulation variables..
