Applied Pin Functions and Applications Internal Equivalent Circuits
Pin Pin Voltage Voltage
No. Name (V) (V)
10 Vcont 0 to 3.0 - Gain control pin of AGC amplifier.
Variable gains are available in
accordance with applied voltage
between 0 to 3.0 V.
11 VCC 2.7 to 3.3 - Supply voltage pin of internal regulator. –
(REG.)
12 GND 0 - Ground pin internal regulator. –
(REG.) This pin should be grounded with
minimum inductance.
Form the ground pattern as widely
as possible to minimize ground impedance.
13 GND 0 - Ground pin of AGC amplifier + I/Q Mixer. –
14 (AGC,
18 MIX) This pin should be grounded with
minimum inductance.
Form the ground pattern as widely
as possible to minimize ground impedance.
15 VCC 2.7 to 3.3 - Supply voltage pin of AGC amplifier + –
(AGC I/Q Mixer.
, MIX)
16 IFout 2.7 to 3.3 - 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.
17 IFoutb 2.7 to 3.3 - Balance output of IFout pin.
The inductor must be attached between
VCC and output pin due to open collector.
19 I VCC/2 - I signal input pin.
Apply bias voltage externally.
Maximum balance input voltage is
1 000 mVP-P (balance).
