Gate control for PA. Adjust Vgg to achieve recommended
bias current. External bypass caps 100 pF, 10 nF and
4.7 µF are required. Apply Vgg bias to either pin 3 or
pin 9.

These pins are not connected internally; however,
all data shown herein was measured with these pins
connected to RF/DC ground externally.
These pins and the exposed ground paddle must be
connected to RF/DC ground.
This pin is AC coupled
and matched to 50 Ohms.
DC voltage of diode biased through external resistor
used for temperature compensation of Vdet. See appli-
cation circuit.
Vdet
RF OUT
DC voltage representing RF output power rectified by
diode which is biased through an external resistor. See
application circuit.
This pin is AC coupled
and matched to 50 Ohms.
