NJG1143UA2

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.
