MXDLN14TP Low Noise Amplifier for GNSS
General Description
MXDLN14TP high gain, Dual-Band low noise
amplifier (LNA) is dedicated to GPS, GLONASS
Galileo and Beidou standards. This product has
an extremely low noise figure of 0.5dB, 18.2dB
gain and excellent linearity.
MXDLN14TP works under a 1.6V to 3.6V single
power supply while consumes 3.3 mA current, in
power down (PD) mode, the power consumption
will be reduced to less than 1uA.
MXDLN14TP uses a small 1.1mm x 0.7mm x
0.45mm LGA 6-pin package.
