MXDLN16GX
Low Noise GPS Amplifier
General Description
MXDLN16GX 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.
MXDLN16GX works under a 1.1V to 2.85V single
power supply while consumes 7.5 mA current, in
power down (PD) mode, the power consumption
will be reduced to less than 1uA.
MXDLN16GX uses a small 1mm×1.5mm×0.75mm
DFN 6-pin package.
Features
High Gain: 19dB
Low noise figure 0.6dB @ 1575.42MHz
Low operation current 6mA & PD current less
than 1uA
3.5mA current under 1.2V power supply
Single supply voltage range 1.1V to 2.85V
Small package 1mm×1.5mm×0.75mm
Low cost BOM
Lead-Free and RoHS-Compliant
Applications
Automotive Navigation
Personal Navigation Device (PND)
Cell Phone with GPS
MID/PAD with GPS
