Description
M/A-COM’s AT90-0001 is a GaAs FET 5-bit digital
attenuator 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 pack-
age. Due to superior grounding techniques this digi-
tal attenuator offers superior performance to 6 GHz.
The AT90-0001 is ideally suited for use where accu-
racy, fast speed, very low power consumption and
low costs are required.
