Description
Power down for the IC. V
PD
=2.8V +/- 0.1V turns on the part.
V
PD
<0.9V turns off the Part. External RF bypassing is required. The
trace length between the pin and the bypass capacitors should be min-
imized. The ground side of the bypass capacitors should connect
immediately to ground plane. Nominal current required for V
PD
=2.8V
is 8.5 mA typical and 12 mA Max (@V
PD
=2.9 V).

NC
RF IN
No connection. This pin is typically left unconnected or grounded.
RF input pin. This pin is DC-coupled and matched to 50
at 1880MHz.

GND1
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
See pin 6.

GND2
GND2
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
Amplifier Output pin. This pin is an open-collector output. It must be
biased to either V
CC
or pin 7 through a choke or matching inductor.
This pin is typically matched to 50
with a shunt bias/matching induc-
tor and series blocking/matching capacitor. Refer to application sche-
matics.
