NJG1148MD7
5GHz BAND LOW NOISE AMPLIFIER GaAs MMIC
I GENERAL DESCRIPTION
NJG1148MD7 is a 5GHz band low noise amplifier GaAs MMIC
designed for wireless LAN, wireless image transmission and
Intelligent Transport System.
The NJG1148MD7 has a LNA pass-through function to select
high gain mode or low gain mode by low control voltage operation.
Within the wide dynamic range from 4.9~5.95GHz, the
NJG1148MD7 achieves low noise figure and high linearity with
fewer external components. The ESD protection circuits are
integrated into the MMIC. They achieve high ESD protection
voltage.
A small and ultra-thin package of EQFN14-D7 is adopted.
