NJG1129MD7

UHF BAND LOW NOISE AMPLIFIER GaAs MMIC

!

GENERAL DESCRIPTION

The NJG1129MD7 is a low noise amplifier GaAs MMIC

designed for mobile digital TV application (470~770 MHz).

This IC has a LNA pass-through function to select high

gain mode or low gain mode by single bit control.

Also, the ESD protection circuit is integrated into the IC to

achieve high ESD tolerance.
