DESCRIPTIONS

1

CTL2

High-impedance C-MOS input terminal. This terminal is set to High-Level by

connect this terminal by 100K

Ω resistor with GND terminal or V

2

CTL3

High-impedance C-MOS input terminal. This terminal is set to High-Level by

connect this terminal by 100K

Ω resistor with GND terminal or V

3

Negative voltage supply terminal. The negative voltage (-3.5~-2.0V) have to

be supplied on transmitting. Otherwise negative voltage of -2.5~0V can be

used or this terminal can be stayed open, because internal level of this

terminal is automatically set to GND level on receiving. The bypass capacitor

have to be connected with GND terminal for excellent RF performance.

4

EXT2

RF receiving port. An external capacitor of 56pF~100pF is required to block

6

EXT1

RF transmitting/receiving port. An external capacitor of 56pF~100pF is

8

TX

RF transmitting port. An external capacitor of 56pF~100pF is required to

10

TER2

ANT1 termination port. The influence of ANT1 port to ANT2 port is

suppressed by terminating this port by an appropriate termination. An

11

ANT1

RF transmitting/receiving port. An external capacitor of 56pF~100pF is

13

RX

RF receiving port. An external capacitor of 56pF~100pF is required to block

15

ANT2

RF receiving port. An external capacitor of 56pF~100pF is required to block

17

TER1

ANT2 termination port. The influence of ANT2 port to ANT1 port is

suppressed by terminating this port with appropriate termination. An external

19

Positive voltage supply terminal. The positive voltage (2.7~5.0V) have to be

supplied. The bypass capacitor have to be connected with GND terminal for

excellent RF performance.
