Description

M/A-COM’s AT-109 is a GaAs MMIC voltage variable

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

mount plastic package. The AT-109 is more linear than

the higher attenuation range AT-108. The AT-109 is ide-

ally suited for use where linear attenuation fine tuning

and very low power comsumption are required. Typical

applications include radio, cellular, GPS equipment and

automatic gain/level control circuits.

The AT-109 is fabricated with a monolithic GaAs MMIC

using a mature 1-micron process. The process features

full chip passivation for increased performance and reli-

ability.
