Description

M/A-COM's AT-273 is a GaAs FET digital attenuator

with a 16.0 dB minimum step size and a 32 dB total

attenuation range. This attenuator and integral TTL driver

is in a hermetically sealed ceramic 16-lead surface mount

package. The AT-273 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.
