MXDLN16GELow Noise GPS Amplifier
General Description
Features
MXDLN16GE high gain, low noise amplifier(LNA)
is dedicated to GPS, GLONASS GalileoandBeidou
standards. This product has an extremely low
noise figure of 0.6dB, 19dB gain and excellent
linearity.
High Gain: 19dB
Low noise figure 0.6dB @ 1575.42MHz
Low operation current 6mA & PD current less
than 1uA
MXDLN16GE 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.
3.5mA current under 1.2V power supply
Single supply voltage range 1.1V to 2.85V
Small package 1mm×1.5mm×0.75mm
MXDLN16GE uses a small 1mm×1.5mm×0.75mm
DFN 6-pin package.
Low cost BOM
Lead-Free and RoHS-Compliant
Applications
Automotive Navigation
Personal Navigation Device (PND)
Cell Phone with GPS
MID/PAD with GPS
