Function and Application
Internal Equivalent Circuit
1
GNDlna
Ground pin of LNA
2
LNAin
Input pin of low noise amplifier. It is a
single-ended open collector design.
Capacitive coupling is required; external
matching will improve gain or NF.
3
VCCrf
Supply voltage pin of LNA, RF mixer and VCO
voltage regulator.
4
GNDlo
Ground pin of 1st LO Oscillator circuit and RF
Mixer.
5
6
1stLO-OSC1
1stLO-OSC2
Pin 5 & 6 are base pins of the differential
amplifier for 1st LO oscillator. These pins
require an LC (varacator) tank circuit to
oscillate at around 1400 MHz.
7
VCClo
Supply voltage pin of oscillator circuit for
1st LO Oscillator and RF mixer
8
PDout
This is a current mode charge pump output.
For connection to a passive RC loop filter for driving
external varactor diode of 1stLO-OSC.
9
VCCdig
Supply voltage pin of digital portion of the chip.
10
REFin
Input pin of reference frequency buffer. This pin
should be equipped with external 27 MHz
oscillator (e.g. TCXO).
11
GNDdig
Ground pin of digital portion of the chip.
