  • Description

    The NJG1142KA1 is a wide band low noise amplifier GaAs MMIC designed for mobile TV application. And this amplifier can be tuned to wide frequency (170MHz to 900MHz).The NJG1142KA1 has a LNA pass-through function to select high gain mode or low gain mode by low control voltage operation. The NJG1142KA1 features low current consumption, high linearity. An ultra-small and ultra-thin package of FLP6-A1 is adopted.
