Notes:
1. Measurements at 2 GHz were made on a fixed tuned production test board that was tuned for optimal OIP3 match with reasonable noise figure
at 2.7 V, 10 mA bias. This circuit represents a trade-off between optimal noise match, maximum OIP3 match and a realizable match based on
production test board requirements. Measurements taken above and below 2 GHz were made using a double stub tuner at the input tuned for
low noise and a double stub tuner at the output tuned for maximum OIP3. Circuit losses have been de-embedded from actual measurements.
2. P1dB measurements are performed with passive biasing. Quiescent drain current, I , is set with zero RF drive applied. As P1dB is approached,
dsq
the drain current may increase or decrease depending on frequency and dc bias point. At lower values of I , the device is running close to class
dsq
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 V = 2.7V and I = 5 mA, I increases to 15 mA
DS
dsq
d
as a P1dB of +14.5 dBm is approached.
