Notes:
1. P1dB measurements are performed with passive biasing. Quiescent 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 P1dB and 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.
