Description
M/A-COM’s AT90-0001 is a GaAs FET 5-bit digital at-
tenuator with an integral TTL driver. Step size is 1.0 dB
providing 31 dB total attenuation range. This device is in a
32 lead FQFP-N surface mount package. Due to superior
grounding techniques this digital attenuator offers superior
performance to 6 GHz. The AT90-0001 is ideally suited for
use where accuracy, fast speed, very low power consump-
tion and low costs are required.
