Description

M/A-COM’s AT-113 is a GaAs MMIC voltage

variable absorptive attenuator in a low-cost SOIC 8-

lead surface mount plastic package. The AT-113 is

ideally suited for use where linear attenuation fine

tuning and very low power consumption are

required.

Typical applications include radio, cellular, GPS

equipment and automatic gain/level control circuits.

The AT-113 is fabricated with a monolithic GaAs

MMIC using a mature 1-micron process. The

process features full chip passivation for increased

performance and reliability.
