Features

Description

M/A-COM’s AT-250 is a GaAs MMIC voltage variable absorptive

attenuator in a low cost SOIC 8-lead surface mount plastic pack-

age. The AT-250 is ideally suited for use where attenuation fine

tuning, fast switching and very low power consumption are

re q u i red. Typical applications include radio, cellular, GPS equip-

ment and other Automatic Gain/Level Control circuits.

The AT-250 is fabricated with a monolithic GaAs MMIC using a

m a t u re 1-micron process. The process features full chip passiva-

tion for increased perf o rmance and reliability.
