General Description
MXDLN16G high gain, low noise amplifier (LNA) is dedicated to GPS, GLONASS Galileo and Beidou standards. This product has an extremely low noise figure of 0.6dB, 19dB gain and excellent linearity.
MXDLN16G works under a 1.1V to 3.6V single power supply while consumes 6mA current, in power down (PD) mode, the power consumption will be reduced to less than 1uA.
MXDLN16G uses a small 1mm×1.5mm×0.75mm DFN 6-pin package.
