AT002N5-11

Description

The AT002N5-11 is a GaAs

I C 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.
