Positive voltage supply terminal. The positive voltage (+2.7~+5.0V) have to be supplied. Please connect
a bypass capacitor with GND terminal for excellent RF performance.
ANT2 termination port (1.5GHz band). Please connect this port and GND by appropriate capacitor to
suppress the interference of ANT2 port signal to ANT1 port.
The capacitor works as DC voltage (V
ANT2 termination port (800MHz RX Mode). Please connect this port and GND by appropriate capacitor
to suppress the interference of ANT2 port signal to ANT1 port. The capacitor works as DC voltage (V
blocking.
ANT2 termination port (800MHz TX Mode). Please connect this port and GND by appropriate capacitor
to suppress the interference of ANT2 port signal to ANT1 port. The capacitor works as DC voltage (V
blocking.
RF transmitting/receiving port. An external capacitor is required to block DC voltage (VDD).

RF receiving port. An external capacitor of is required to block DC voltage (V
Negative voltage supply terminal. Please supply negative voltage of -3.5~-2.0V on transmitting state. On
receiving state, this terminal is internally disconnected, so the voltage of this terminal (negative, short, or
open) does not affect to receiving signal quality. The bypass capacitor should be connected between this
terminal and GND for excellent RF performance.
