ASL21X

Medium Gain, Low Noise GPS Amplifier

Features

Description

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.

· 20.5 dB Gain at 1575 MHz

· 0.65 dB NF at 1575 MHz

· Power ON/OFF Function.

· Supply Voltage = 1.8 V
