Descriptions
RF input for the offset mixer. When the offset mixer is not used, this pin
should be opened.
Ground.
IF input for the offset mixer. When the offset mixer is not used, this pin
should be opened.
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.
Lo input for the I/Q modulator (Output for the offset mixer.)
Lo complementary input for the I/Q modulator (Complementary output for
the offset mixer.)
Power supply for the I/Q modulator.
Ground.
Ground.
Ground.
Q signal input for the I/Q modulator.
Q signal complementary input for the I/Q modulator.
I signal complementary input for the I/Q modulator.
I signal input for the I/Q modulator.
Output mode switch. Mode = Open: Low power mode.
Mode = GND: High power mode.
This pin should be connected to ground or left open.
Power supply for the I/Q modulator.
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.
Output for the I/Q modulator. (Open collector)
Open is prohibited when power is supplied to Vcc pin.
Power saving control for the I/Q modulator. When PSQ = L(GND), power
down mode is selected.
Further, increasing the output power level is possible by attaching a resistor
between Pcnt pin and ground externally.
