Description

M/A-COM’s AT-283 is a GaAs FET 5-bit digital attenuator

with a 0.5 dB minimum step size and 15.5 dB total

attenuation. This attenuator and integral TTL driver is in a

hermetically sealed ceramic 16-lead surface mount package.

The AT-283 is ideally suited for use where accuracy, fast

switching, very low power consumption and low

intermodulation products are required. Typical applications

include dynamic range setting in precision receiver circuits

and other gain/leveling control circuits. Environmental

screening is available. Contact the factory for information.
