WIDE BAND LOW NOISE AMPLIFIER GaAs MMIC
GENERAL DESCRIPTION
PACKAGE OUTLINE
The NJG1142KA1 is a wide band low noise amplifier GaAs MMIC
designed for mobile TV application. And this amplifier can be tuned to
wide frequency (170MHz~900MHz).
The NJG1142KA1 has a LNA pass-through function to select high
gain mode or low gain mode by low control voltage operation.
The
NJG1142KA1 features low current consumption, high linearity.
An ultra-small and ultra-thin package of FLP6-A1
is adopted.
