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
required. 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
mature 1-micron process. The process features full chip passiva-
tion for increased performance and reliability.
