NJG1168PCD
GPS Front-End Module
GENERAL DESCRIPTION
The NJG1168PCD is a front-end module (FEM) designed for GPS
applications. Its ultra-low current consumption is particularly suitable for
wearable devices. This FEM offers high gain, low noise figure, high linearity
and very high out-band rejection characteristics brought by included high
performance pre- SAW filter, low noise amplifier (LNA) and post- SAW filter.
This FEM offers very small mounting area by included two SAW filters, only
two external components and very small package HFFP10-CD.

TERMINAL INFORMATION
No. SYMBOL
DESCRIPTION
1
GND
Ground terminal. This terminal should be connected to the ground plane as
close as possible for excellent RF performance.
2 VCTL Control voltage terminal.
3
VDD
Supply voltage terminal. Please connect bypass capacitor C1 with ground as
close as possible.
4
NC(GND)
No connected terminal. This terminal is not connected with internal circuit.
Please connect to the PCB ground Plane.
5 PreIN RF input terminal. This terminal connects to input of pre-SAW filter.
6
GND
Ground terminal. This terminal should be connected to the ground plane as close
as possible for excellent RF performance.
7 PreOUT Pre-SAW filter output terminal. This terminal connects to LNAIN with L1.

Exposed
Pad
LNAIN
RF input terminal. This terminal requires only a matching inductor L1, and
does not require DC blocking capacitor because of integrated capacitor.
NC(GND)
PostOUT
GND
No connected terminal. This terminal is not connected with internal circuit.
Please connect to the PCB ground Plane.
RF output terminal. This terminal requires no DC blocking capacitor since this
terminal has integrated SAW that also works as DC blocking capacitor in
nature.
Ground terminal. This terminal should be connected to the ground plane as close
as possible for excellent RF performance.
