GPS LOW NOISE AMPLIFIER GaAs MMIC
! GENERAL DESCRIPTION
The NJG1143UA2 is a GPS LNA GaAs MMIC featured very samll size, low
noise figure, high gain and low current consumpition. The NJG1143UA2
operates from 1.5V to 3.6V single voltage, has stand-by mode to save the
supply current, and requires only three external components. The
NJG1143UA2 has a on-chip ESD protection. The NJG1143UA2 is available in
a very small, lead-free, halogen-free, 1.0mm x 1.0mm x 0.37 mm, 6-pin
EPFFP6-A2 package.
