OPERATION GUIDE
PIN DESCRIPTION 
Pin name  I/O  Description  Equivalent circuit 
RF I/O 
RF input terminal 
Antenna impedance nominal 50 Ω 
GND I 
GROUND terminal 
The GND pins and the feet of the shield case 
shoud be connected to the wide GND 
pattern. 
VCC I 
Power supply terminal 
DC 3.0 to 5.5 V 
TXSEL I 
TX select terminal 
GND = TXSEL active 
To enable the transmitter circuits, connect 
TXSEL to GND and RXSEL to OPEN or 2.8 
V. 
RXSEL I 
RX select terminal 
GND= RXSEL active 
To enable the receiver circuits, connect 
RXSEL to GND and TXSEL to OPEN or 2.8 
V. 
AF O 
Analogue output terminal 
There is DC offset of approx. 1 V. 
Refer to the specification table for amplitude 
level.
