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 pack-
age. The AT20-0106 is ideally suited for use where
accuracy, fast switching, low power consumption
and low intermodulation products are required. Typi-
cal applications include dynamic range
setting in precision receiver circuits and other gain/
leveling control circuits. Available with enhanced
performance as fully hermetic version. Environmen-
tally screenable as P/N AT-106-PIN.
