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 terrestrial application.
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.
