Gain control pin of AGC amplifier.
Variable gains are available in
accordance with applied voltage
between 0 to 3.0 V.
Supply voltage pin of internal regulator.
Ground pin internal regulator.
This pin should be grounded with
minimum inductance.
Form the ground pattern as widely
as possible to minimize ground impedance.
Ground pin of AGC amplifier + I/Q Mixer.
This pin should be grounded with
minimum inductance.
Form the ground pattern as widely
as possible to minimize ground impedance.
Supply voltage pin of AGC amplifier +
I/Q Mixer.
IF output pin.
The inductor must be attached between
VCC and output pin due to open collector.
Output frequency is 570 MHz which is
3/4 of local signal frequency 760 MHz.
Balance output of IFout pin.
The inductor must be attached between
VCC and output pin due to open collector.
I signal input pin.
Apply bias voltage externally.
Maximum balance input voltage is
1 000 mVP-P (balance).
