1 NJG12KA1 Wide Band Low Noise Amplifier GaAs MMIC GENERAL DESCRIPTION The NJG12KA1 is a fully matched wide band low noise amplifier GaAs MMIC for terrestrial application. To achieve wide dynamic range, the NJG12KA1 offers high gain mode and low gain mode. Selecting high gain mode for weak signals, the NJG12KA1 helps improve receiver sensitivity through high gain and low noise figure. Selecting low gain mode for strong signals, it bypasses LNA circuit to offer higher linearity. An small and ultra-thin package of FLP6-A1 is adopted.
