Description
The AT002N5-01 is a GaAs IC FET absorptive attenuator.
It provides up to 50 dB variable attenuation from
DC–3 GHz under non-reflective conditions. This
attenuator is recommended for fast response AGC circuits
for commercial and high reliability applications. The
AT002N5-10 is the gullwing version of this device for
surface mount applications.
