Description

M/A-COM’s AT20-0106 is a GaAs FET 6-bit digital

attenuator with a 1 dB minimum step size and 50 dB

total attenuation. This attenuator and integral TTL

driver is in a ceramic 24-lead surface mount pack-

age. The AT20-0106 is ideally suited for use where

accuracy, fast switching, low power consumption

and low intermodulation products are required. Typi-

cal

applications

include

dynamic

range

setting in precision receiver circuits and other gain/

leveling control circuits.

Available with enhanced

performance as fully hermetic version. Environmen-

tally screenable as P/N AT-106-PIN.
