Description

M/A-COM’s AT20-0273 is a GaAs FET digital

attenuator with a 16 dB minimum step size and 32

dB total attenuation. This attenuator and integral

TTL driver is in a sealed ceramic 16-lead surface

mount package. The AT20-0273 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. Available with en-

hanced performance as fully hermetic version. Envi-

ronmentally screenable as P/N AT-273-PIN.
