Description

M/A-COM's AT20-0107 is a GaAs FET 6-bit digital

attenuator with a 0.5 dB minimum step size and a

31.5 dB total attenuation. This attenuator and inte-

gral TTL driver is in a ceramic 24-lead surface mount

package. The AT20-0107 is ideally suited for use

where accuracy, fast speed, 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 enhanced

performance as fully hermetic version. Environmen-

tally screenable as P/N AT-107-PIN.
