Pin no.
Symbol
I/O
Descriptions
1
RFin
I
RF input for the offset mixer. When the offset mixer is not used, this pin
should be opened.
2
GND
—
Ground.
3
IFin
I
IF input for the offset mixer. When the offset mixer is not used, this pin
should be opened.
4
VccM
—
Power supply for the offset mixer. Power-on/off is possible indepently to the
modulator. When the offset mixer is not used, this pin should be switched
OFF.
5
Lo
I/O
Lo input for the I/Q modulator (Output for the offset mixer.)
6
Lox
I/O
Lo complementary input for the I/Q modulator (Complementary output for
the offset mixer.)
7
Vcc
—
Power supply for the I/Q modulator.
8
GND
—
Ground.
9
GND
—
Ground.
10
GND
—
Ground.
11
Q
I
Q signal input for the I/Q modulator.
12
XQ
I
Q signal complementary input for the I/Q modulator.
13
XI
I
I signal complementary input for the I/Q modulator.
14
I
I
I signal input for the I/Q modulator.
15
Mode
—
Output mode switch. Mode = Open: Low power mode.
Mode = GND: High power mode.
This pin should be connected to ground or left open.
16
Vcc
—
Power supply for the I/Q modulator.
17
PSM
I
Power saving control for the offset mixer. When PSM = L(GND), power
down mode is selected. When the offset mixer is not used, this pin should
be connected to Vcc voltage level or ground.
18
Out
O
Output for the I/Q modulator. (Open collector)
Open is prohibited when power is supplied to Vcc pin.
19
PSQ
I
Power saving control for the I/Q modulator. When PSQ = L(GND), power
down mode is selected.
20
Pcnt
—
Further, increasing the output power level is possible by attaching a resistor
between Pcnt pin and ground externally.
