Description

M/A-COM’s AT-255 is a GaAs MMIC voltage

variable absorptive attenuator in a low cost SOT-25

surface mount plastic package. The AT-255 is

ideally suited for use where variable 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-255 is fabricated using a mature 1-micron

GaAs MESFET process. The process features full

chip passivation for increased performance and

reliability.
