1 NJGPCD GPS Front-End Module GENERAL DESCRIPTION The NJGPCD 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 HFFP-CD.
