AT002S3-11
Description
The AT002S3-11 is a GaAs IC FET absorptive bridged “T”
attenuator.This attenuator operates from 0.4–2.5 GHz and
provides up to 35 dB of attenuation.The key feature of this
attenuator is the requirement of only one “positive”control
voltage.Blocking capacitors are required on the RF ports.
