AR8159
Low Noise Amplifier for GPS/GNSS



 
Product Overview
The AR8159 is a high gain, low noise amplifier (LNA) for GPS, GLONASS, Galileo, and Compass applications. It operates from 1.6V to 3.6V and achieves 18.5 dB gain and 0.8 dB noise figure while giving a high linearity.
 
The current consumption of AR8159 in enable mode and disable mode are 5.8mA and 1uA respectively. The AR8159 is in a very small, lead-free, RoHS-compliant, 1.5mm x 1.0mm x 0.75mm 6-pin uDFN package. It requires low bill of materials, including one external matching inductor, one bypass capacitor and one DC blocking capacitor. The AR8159 is the best solution to improve the GPS receiver performance obviously and easily.
