Function and Application
3 RX-MIXout
1.68
Output pin of RF mixer.
1st IF filter must be inserted
between pin 1 & 3.
4 VCC (RF-MIX) 2.7 to 3.3
Supply voltage pin of RF mixer
block. This pin must be
decoupled with capacitor
(eg. 1 000 pF).
5 RF-MIXin
1.20
Input pin of RF mixer.
1 575.42 MHz band pass filter
can be inserted between pin 5
and external LNA.
6 GND (RF-MIX)
0
Ground pin RF mixer.
7 VCC
2.7 to 3.3
Supply voltage pin of differential
(1stLO-OSC)
amplifier for 1st LO oscillator
circuit.
8 1stLO-OSC1
9 1stLO-OSC2
1.88
Pin 8 & 9 are each base pin of
differential amplifier for 1st LO
oscillator. These pins should be
1.88
equipped with LC and varactor
to oscillate on 1636.80 MHz as
VCO.
10 GND
0
(1stLO-OSC)
Ground pin of differential
amplifier for 1st LO oscillator
circuit.
11 VCC (phase
2.7 to 3.3
Supply voltage pin of phase
detector)
detector and active loop filter.

difference
Pins of active loop filter for
tuning voltage output.
The active transistors
configured with darlington pair
are built on chip. Pin 14 should
be pulled down with external
resistor. Pin 12 to 13 should be
equipped with external RC in
order to adjust dumping factor
and cutoff frequency. This
tuning voltage output must be
connected to varactor diode of
1st LO-OSC.
15 GND (phase
0
detector)
Ground pin of phase detector +
active loop filter.
