Description

M/A-COM’s AT-113 is a GaAs MMIC voltage variable

absorptive attenuator in a low cost SOIC 8-lead surface mount

plastic package. The AT-113 is ideally suited for use where

linear attenuation fine tuning and very low power consumption

are required.

Typical applications include radio, cellular, GPS equipment and

automatic gain/level control circuits.

The AT-113 is fabricated with a monolithic GaAs MMIC using

a mature 1-micron process. The process features full chip

passivation for increased performance and reliability.
