AR8125
Low Noise Amplifier for GPS/GNSS





Product Overview

The AR8125 is a high gain, low noise amplifier (LNA) for GPS, GLONASS, Galileo, and COMPASS/BeiDou 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 AR8125 in enable mode and disable mode are 5.6mA and 1uA respectively. The AR8125 is in a very small, lead-free, RoHS-compliant, 1.1mm x 0.9mm x0.45mm 6-pin uDFN package. It requires low bill of materials, including one external matching inductor, one bypass capacitor and one DC blocking capacitor. The AR8125 is the best solution to improve the GPS receiver performance obviously and easily
