Description
M/A-COM’s AT20-0273 is a GaAs FET digital
attenuator with a 16 dB minimum step size and 32 dB total
attenuation. This attenuator and integral TTL driver is in a
sealed ceramic 16-lead surface mount package. The
AT20-0273 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. Available with
enhanced performance as fully hermetic version.
Environmentally screenable as P/N AT-273.
