Product Description

The AL1 is a high intercept, low-noise amplifier

designed for wide dynamic range receiver appli-

cations. Exceptional low noise performance and

low input VSWR can be achieved simultane-

ously with the use of low cost SMT compo-

nents to implement the input-matching net-

work. The AL1 operates from a single +5 V

supply voltage, has a DC blocking capacitor on

the RF output, and is available in a low cost

SOIC-8 package. The AL1 is designed for wire-

less local loop, wireless LAN, and other appli-

cations within the ISM band.
