TERMINAL INFORMATION  
PIN No.

VSS  
DESCRIPTION  
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.

VDD  
High-impedance C-MOS input terminal. This terminal is set to High-Level  
(+2V~VDD) or Low-Level (+0.6V~0V). If the voltage level of this terminal is  
unstable, please connect a resistor (100KW) with GND terminal or VDD terminal.  
High-impedance C-MOS input terminal. This terminal is set to High-Level  
(+2V~VDD) or Low-Level (+0.6V~0V). If the voltage level of this terminal is  
unstable, please connect a resistor (100KW) with GND terminal or VDD terminal.  
High-impedance C-MOS input terminal. This terminal is set to High-Level  
(+2V~VDD) or Low-Level (+0.6V~0V). If the voltage level of this terminal is  
unstable, please connect a resistor (100KW) with GND terminal or VDD terminal.  
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.

TER1  
ANT2 termination port. Please connect this port and GND by appropriate  
capacitor (5pF) to suppress the interference of ANT2 port signal to ANT1 port.  
The capacitor works as DC voltage (VDD) blocking.
