The AT004N3-11 is a GaAs IC FET non-reflective bridged

“T” attenuator. This device provides over 30 dB of

“matched” attenuation with the input and output VSWR

less than 1.5:1 under all attenuation values. The

applications for these fast attenuators are AGC circuits and

variable level control in high reliability and

telecommunication systems.
