ASL20G
Low Noise GPS, GLONASS, Galileo and Compass Amplifier
Features
GPS, GLONASS, Galileo and
Compass LNA
21 dB Gain at 1575 MHz
0.65 dB NF at 1575 MHz
Power ON, OFF Function
Supply Voltage = 1.8 ~ 5.0 V
Description
ASL20G is an LNA for GPS, GLONASS, Galileo,
Compass and SiriusXM in mobile equipment which
requires lower current and lower noise. Power
saving function is built in. Low noise performance is
kept over the wide range of power enable voltage
and DC power supply voltage.
