rf power and drain current
Most of the MMIC power amplifiers operates in Class AB, so the saturation current is few times greater than quiescent current.
The drain bias voltage goes direct to the drain through the choke. Generally there is no resistor added in series with the choke, because this will decrease the efficiency.
Some manufacturers uses as a choke, for high frequency MMICs (fo>1700MHz), pieces of internal bond wires (inside of the package, between die and pins). The inductance of these bond wires is very predictable, having also low DC resistance.
