AT-283 Description
M/A-’s AT-283 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 is ideally suited for use where accuracy, fast switching, very low power consumption and low intermodulation products are required.
