General Description
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.
