How to get S parameter for FET transistor in MWO?

Hey, I'm designing a class AB amplifier and need to know the S parameter first, any one can help me to come up with a schematics that I can use to get proper Smith chart from MWO？

Thnaks！

In your schematic add a graph, right click and chose a measurement, Linear, S paramaters. There is an option in MWO that you can save the simulated S parameters as a S1P or S2P Touchstone file.
