NJG1146KG1

WIDE BAND LOW NOISE AMPLIFIER GaAs MMIC

I

GENERAL DESCRIPTION

The NJG1146KG1 is a fully matched wide band low noise

amplifier GaAs MMIC for digital TV applications.

To achieve wide dynamic range, the NJG1146KG1 offers

high gain mode and low gain mode. Selecting high gain mode

for weak signals, the NJG1146KG1 helps improve receiver

sensitivity through high gain and low noise figure.

Selecting low gain mode for strong signals, it bypasses LNA

circuit to offer higher linearity.

An small and ultra-thin package of ESON6-G1 is adopted.
