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 package. 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

equipment and other automatic gain/level control

circuits.

Pin Configuration

The AT-250 is fabricated with a monolithic GaAs

MMIC using a mature 1-micron process. The

process features full chip passivation for increased

performance and reliability.
