Notes:
1. Measurements made on a fixed toned production test board that was tuned for optimal gain match with reasonable noise figure at 4 V,
60 mA bias. This circuit represents a trade-off between 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.
2. P1dB measurements are performed with passive biasing. Quicescent drain current, IDSQ, is set with zero RF drive applied. As P1dB is
approached, the drain current may increase or decrease depending on frequency and dc bias point. At lower values of IDSQ the device
is running closer to class B as power output approaches P1dB. This results in higher PAE (power added efficiency) when compared to
a device that is driven by a constant current source as is typically done with active biasing. As an example, at a VDS = 4 V and
IDSQ␣ =␣ 10␣ mA, Id increases to 62 mA as a P1dB of +19 dBm is approached.
