Description
Interface Schematic
Output pin for Receive mode. VSWR is 1.1:1 when Receive mode is
selected and highly capacitive when Transmit mode is selected.
Ground connection. For best performance, keep traces physically short
and connect immediately to the ground plane.

Input pin for Transmit mode. The input VSWR is 1.1:1 when Transmit mode
is selected and highly capacitive when Receive mode is selected.
Transmit Mode/Receive Mode control pin. A “low” level chooses Receive
mode; a “high” level chooses Transmit mode. CMOS logic may be used to
drive the control input.
Input/Output pin from/to antenna and power supply pin. This pin must be
biased with VDD through a resistor.
