NJG1155UX2
GNSS LOW NOISE AMPLIFIER GaAs MMIC
I
GENERAL DESCRIPTION
The NJG1155UX2 is a LNA GaAs MMIC designed for GNSS
applications, like GPS, Galileo, GLONASS and COMPASS. The
NJG1155UX2 is featured low noise figure, and operates from 1.5V to
3.3V single voltage. The NJG1155UX2 has stand-by mode to save the
supply current, has the on-chip ESD protection devices.
The NJG1155UX2 achieves ultra small mounting area by only two
external components and ultra small package that is lead-free and
halogen-free 6-pin EPFFP6-X2 package.

DESCRIPTION
Ground terminal. This terminal should be connected to the ground plane as
close as possible for excellent RF performance.
Supply voltage terminal. Please connect bypass capacitor C1 with ground as
close as possible.
RF output terminal. This terminal requires no DC blocking capacitor since this
IC has internal output matching circuit including DC blocking capacitor.
Ground terminal. This terminal should be connected to the ground plane as
close as possible for excellent RF performance.
RF input terminal. This terminal requires only a matching inductor L1, and does
not require DC blocking capacitor.
