Description

M/A-COM’s AT-283-PIN is a GaAs FET 5-bit digital

attenuator with a 0.5 dB minimum step size and 15.5

dB total attenuation. This attenuator and integral

TTL driver is in a hermetically sealed ceramic 16

lead surface mount package. The AT-283-PIN is

ideally suited for use where accuracy, fast switching,

very low power consumption and low intermodula-

tion products are required. Typical applications in-

clude dynamic range setting in precision receiver

circuits and other gain/leveling control circuits. Envi-

ronmental screening is available. Contact the fac-

tory for information.
