Pin Description
PIN
NAME
FUNCTION
A1
RFIN/SHDN RF Input and Shutdown Logic Input. AC-couple the RF input to this pin and apply the shutdown logic
input through a resistor. Drive low to turn the part off, drive high, or connect to VCC to turn the part on.
A2
VCC
Power-Supply Pin. Bypass to GND with a capacitor as close to the bump as possible.
Ground Connection. Multiple ground vias placed as close to the IC as possible should be used to
B1
GND
connect the ground pin to the ground plane. Connect to PC board ground plane with as low
inductance as possible.
