  • Description

    The 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 to 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.
