NJG1144KA1

NJG1144KA1 GPS LOW NOISE AMPLIFIER GaAs MMIC GENERAL DESCRIPTION The NJG1144KA1 is a low noise amplifier GaAs MMIC designed for GPS, GALILEO, and GLONASS. 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. An ultra-small and easy mounting package of FLP6-A1 is adopted. PACKAGE OUTLINE NJG1144KA1 FEATURES Wide supply voltage range Low current consumption High gain Low noise figure High Input IP3 Small package Lead -free and halogen-free PIN CONFIGURATION 1.5V~3.6V 3.5mA typ. @ VDD=2.85V 1.8mA typ. @ VDD=1.8V 21.0dB typ. @ f=1575MHz, VDD=2.85V 0.65dB typ. @ f=1575MHz, VDD=2.85V -2.0dBm typ. @ f=1575MHz, VDD=2.85V FLP6-A1 (package size: 1.6mm x 1.6mm x 0.55mm typ.)
