Description
M/A-COM's AT20-0107 is a GaAs FET 6-bit digital
attenuator with a 0.5 dB minimum step size and a
31.5 dB total attenuation. This attenuator and inte-
gral TTL driver is in a ceramic 24-lead surface mount
package. The AT20-0107 is ideally suited for use
where accuracy, fast speed, 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. Environmen-
tally screenable as P/N AT-107-PIN.
