AT004N3-11
Description
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.
