Momentum Simulation and DC

Attached is a schematic of a DC test of a momentum simulation. The copper symbol is an input matching network to a FET. The predicted current is 35 mA, obviously incorrect.

Did I set up the model incorrectly?

Thanks for any help!

Make sure you run the Momentum simulation starting from DC, or the S-parameters will be extrapolated, possibly giving erroneous DC results when the Momentum data is re-used.
