ASB ASL21X

ASL21X
Medium Gain, Low Noise GPS Amplifier
Features
Description
· 20.5 dB Gain at 1575 MHz
ASL21X is an LNA for GPS 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.
· 0.65 dB NF at 1575 MHz
· Power ON/OFF Function.
· Supply Voltage = 1.8 V
