NJG1144KA1 GNSS LOW NOISE AMPLIFIER GENERAL DESCRIPTION The NJG1144KA1 is a low noise amplifier GaAs MMIC designed for GNSS (Global Navigation Satellite Systems). This amplifier achieves high gain and a good balance between ultra-low noise figure and excellent VSWR, while low current consumption and high IP3, respectively. The NJG1144KA1 operates from +1.5V to +3.6V supply voltage range and current consumes is as low as 3.5mA. Also, the ESD protection circuit is integrated into the IC to achieve high ESD tolerance. An ultra-small and easy mounting package of FLP6-A1 is adopted. PACKAGE OUTLINE NJG1144KA1 APPLICATIONS GNSS applications, like GPS, Galileo, GLONASS and COMPASS.
