Ground the Pin14. Input a signal (–45
dBm) to the Pin16 and measure an out-
put change between the Pins 28 and 1
when I
L
changes from 80mA to 30mA.
Ground the Pin15. Input a signal
(–50dBm) to the Pin24 and measure
the output between the Pins 25 and 26.
Ground the Pin15. Input a signal
(–50dBm)
to the Pin24 and measure the output distor-
tion factor between the Pins 25 and 26.

=20mA).
1V reference coltage output pin.
Connect to GND via 47
μ
F. No current
is allowed to be input/output from this
pin.
External battery connection pin.
Connect the 3 to 6V battery to GND.
Connect to GND directly when the BT
function is not used.
Transmitter output.
Transmitter gain control pin.
Controls the gain and frequency charac-
teristic of the transmitter system with
external C and R.
Automatic pad control pin.
Capable of controlling the pad operating
point with the external resistor.
