bias. This circuit represents a trade-off between an optimal noise match, maximum gain match and a realizable match based on production test
board requirements. Circuit losses have been de-embedded from actual measurements.
drain current may increase or decrease depending on frequency and dc bias point. At lower values of I
as power output approaches P
by a constant current source as is typically done with active biasing.
