Pin Function Description
Interface Schematic
1
GND
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
2
GND
Same as pin 1.
3
RF IN
RF input pin. This pin is internally DC blocked and thus does not
require an external blocking capacitor. The input impedance of this pin
is internally matched to 50Ω using resistive feedback.
