Features

Description

M/A-COM’s AT-259 is a GaAs MMIC voltage variable absorp-

tive attenuator in a low cost SOT/143 4-Lead surface mount

plastic package. The AT-259 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,

c e l l u l a r, GPS equipment and other Automatic Gain/Level

C o n t rol circuits.

The AT-259 is fabricated with a monolithic GaAs MMIC using

a mature 1 micron process. The process features full chip pas-

sivation for increased perf o rmance and reliability.

Attenuation: 12 dB at 1 GHz
