ATF-35143 Typical Performance Curves, continued
Notes:
1. Measurements made on a fixed tuned test fixture that was tuned for noise figure at 2 V 15mA bias. This circuit represents a trade-off between
optimal noise match, maximum gain match and a realizable match based on production test requirements. Circuit losses have been de-
embedded from actual measurements.
2. 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. As an example, at a VDS = 4V and IDSQ = 5 mA, Id increases to 30 mA as a P1dB of +15
dBm is approached.
