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.
