Description

M/A-COM’s AT20-0263 is a GaAs FET 5-bit digital

attenuator with a 1 dB minimum step size and 31 dB

total attenuation. This attenuator and integral TTL

driver is in a ceramic 16-lead surface mount pack-

age. The AT20-0263 is ideally suited for use where

accuracy, fast switching, very low power consump-

tion and low intermodulation products are required.

Typical applications include dynamic range setting in

precision receiver circuits and other gain/leveling

control circuits. Available with enhanced perform-

ance as fully hermetic version. Environmentally

screenable as P/N AT-263-PIN.
