Features

Description

Package Style: SOT363

Typical Performance

ASL21X is an LNA for GPS, GLONASS, Galileo,

Compass and XM 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.
