nTERMINAL INFORMATION
PIN No.
SYMBOL
DESCRIPTION
1
VSS
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.
2
CTL3
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 (100K
Ω) with GND terminal or V
DD terminal.
3
CTL2
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 (100K
Ω) with GND terminal or V
DD terminal.
5
CTL1
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 (100K
Ω) with GND terminal or V
DD terminal.
6
VDD
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.
10
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.
12
RX
RF receiving port. An external capacitor (56pF~100pF) is required to block DC
voltage (VDD) .
14
ANT1
RF transmitting/receiving port. An external capacitor (56pF~100pF) is required to
block DC voltage (VDD) .
16
ANT2
RF receiving port. An external capacitor (56pF~100pF) is required to block DC
voltage (VDD).
17
TER2
ANT2 termination port. Please connect this port and GND by appropriate
capacitor (10pF) to suppress the interference of ANT1 port signal to ANT2 port.
The capacitor works as DC voltage (VDD) blocking.
19
TX
RF transmitting port. An external capacitor of 56pF~100pF is required to block
DC voltage (VDD).
21
EXT1
RF transmitting/receiving port. An external capacitor of 56pF~100pF is required
to block DC voltage (VDD).
23
EXT2
RF receiving port. An external capacitor of 56pF~100pF is required to block DC
voltage (VDD).
4, 7, 8, 9,
11, 13, 15,
18, 20, 22,
24
GND
Ground terminal. Please connect this terminal with ground plane as close as
possible for excellent RF performance.
