Description
M/A-COM’s AT-106 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 hermetically
sealed ceramic 24-lead surface mount package. The AT-
106 is ideally suited for use where accuracy, fast switching,
very low power consumption and low intermodulation
products are required. Typical applications include dy-
namic range setting in precision receiver circuits and other
gain/leveling control circuits. Environmental screening is
available. Contact the factory for information.
