Function
RF IN
Description
RF input pin. This pin is DC coupled.
Interface Schematic
2
GND1
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
This pin is used to control the bias current. An external resistor can be
used to set the bias current for any V
BIAS
voltage. See table with evalu-
ation board schematic.

4
RF OUT
Amplifier 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 typi-
cally matched to 50
with a shunt bias/matching inductor and series
blocking/matching capacitor. Refer to application schematics.
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
