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.
