NJG1129MD7
UHF BAND LOW NOISE AMPLIFIER GaAs MMIC
I 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.
I APPLICATIONS
Wide band application from 470MHz to 770MHz
Mobile TV and Digital TV applications
Mobile phone and tablet PC applications
