I PACKAGE OUTLINE

The NJG1157PCD is a front-end module (FEM) designed for GPS and

GLONASS applications. This FEM offers high gain, low noise figure, high

linearity and high out-band rejection characteristics brought by included high

performance pre-SAW filter, low noise amplifier (LNA) and post-SAW filter.

This FEM can operate from 1.5V to 3.3V single voltage in -40 to 105°C. This

FEM has stand-by mode to save current consumption.

This FEM offers very small mounting area by included two SAW filters, only

two external components and very small HFFP10-CD package that is

2.5x2.5mm.
