DESCRIPTION
1
BIAS
Resistor Bias Control. Connect a resistor, R
BIAS
,
from BIAS to ground. R
BIAS
sets IP3 and supply
current. The current through this pin is approximately 60mV divided by R
BIAS
(see
Applications
Information
).
2, 5
GND
Ground. For optimum performance, provide a low-inductance connection to the ground plane.
3
RFIN
Amplifier Input. AC-couple to this pin with a DC blocking capacitor. External matching network is
required for optimum performance.
4
V
CC
Supply Voltage. Bypass with a capacitor directly to ground at the supply pin. Refer
to V

section for more information.
6
RFOUT
Amplifier Output. AC-coupled internally.
