GNSS LOW NOISE AMPLIFIER GENERAL DESCRIPTION The NJG11KA1 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 IP, respectively. The NJG11KA1 operates from +1.V to +.V supply voltage range and current consumes is as low as.ma. Also, the ESD protection circuit is integrated into the IC to achieve high ESD tolerance. An ultra-small and easy mounting package of FLP-A1 is adopted. PACKAGE OUTLINE NJG11KA1 APPLICATIONS GNSS applications, like GPS, Galileo, GLONASS and COMPASS.
