AT002N5-11
Description
The AT002N5-11 is a GaAs IC FET absorptive
attenuator. This device provides up to 50 dB variable
attenuation from DC–3 GHz. Attenuation can be
controlled by varying each of the two control bias voltages
from 0 to -5 V. This attenuator is recommended for fast
response AGC circuits in commercial and high reliability
applications.
