Description
Supply connection. An external bypass capacitor may be required in
some applications.
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
RF input pin. This pin is DC coupled and matched to 50
at 2.4GHz.
Interface Schematic
See pin 3.

Power down pin.This pin enables the bias to the amplifier. To turn the
amplifier on, this pin should be connected to V
CC
. Connecting this pin
to ground, will turn the amplifier off and reduce the current draw to
below 1
μ
A. This pin is a CMOS input. There is no DC current draw
other than the transient current required to charge or discharge the
gate capacitance (less than 5pF).
LNA Output pin.This pin is an open-collector output. It must be biased
to V
CC
through a choke or matching inductor. This pin is typically
matched to 50
with a shunt bias/matching inductor and series block-
ing/matching capacitor. Refer to application schematics.
