NJG1145UA2
WIDE BAND LOW NOISE AMPLIFIER GaAs MMIC
I GENERAL DESCRIPTION
The NJG1145UA2 is a fully matched wide band low noise
amplifier GaAs MMIC for digital TV and BS/CS applications. This
amplifier covers VHF, UHF, and L bands.
To achieve wide dynamic range, the NJG1145UA2 offers high
gain mode and low gain mode. Selecting high gain mode for weak
signals, the NJG1145UA2 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.
In high gain mode, the NJG1145UA2 achieves high gain and
high IIP3 across the band.
The ESD protection circuits are integrated into the MMIC. They
achieve high ESD protection voltage.
An ultra-small and ultra-thin package of EPFFP6-A2 is adopted.
