Description
Interface Schematic
1RX OUT
Output pin for Receive mode. VSWR is 1.1:1 when Receive mode is
selected and highly capacitive when Transmit mode is selected.
2GND
Ground connection. For best performance, keep traces physically short
and connect immediately to the ground plane.
3TX IN
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.
4TX/RX
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.
5
ANT I/O
Input/Output pin from/to antenna and power supply pin. This pin must
be biased with VDD through a resistor.
