Description
M/A-COM’s AT-263 is a GaAs FET 5-bit digital
attenuator with a 1 dB minimum step size and 31 dB total
attenuation. This attenuator and integral TTL driver is in a
hermetically sealed ceramic 16-lead surface mount package.
The AT-263 is ideally suited for use where accuracy, fast
switching,
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.
Environmental
screening is available. Contact the factory for information.
