Function
PD
Description
For low noise amplifier applications, this pin is used to control the bias
current. See plots for bias current settings.
Interface Schematic
For driver amplifier applications, this is the Power Down pin for the IC.
V
PD
=2.8V +/- 0.1V is required for proper operation. 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 minimized. The
ground side of the bypass capacitors should connect immediately to
ground plane. Nominal current required for V
PD
=2.8V is 2.0mA typical
and 3.0mA Max (@ V
PD
=2.9V).

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 836MHz.
4
GND1
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
See pin 2. This pin is typically grounded.

GND2
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
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.
