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

running close 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 V
2.7V and I
a P1dB of +14.5 dBm is approached.
