Description
M/A-COM’s AT20-0106 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
ceramic 24-lead surface mount package. The AT20-0106 is
ideally suited for use where accuracy, fast switching, 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-106.
