Description
Interface Schematic
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.

BIAS GND2
PWR SEN
The PWR SEN and PWR REF pins can be used in conjunction with an exter-
nal feedback path to provide an RF power control function for the RF2163.
The power control function is based on sampling the RF drive to the final
stage of the RF2163.

GND
RF output and bias for the output stage. The power supply for the output
transistor needs to be supplied to this pin. This can be done through a
quarter-wave length microstrip line that is RF grounded at the other end, or
through an RF inductor that supports the required DC currents.
