Description The AT006N3-01 is a GaAs IC FET non-reflective bridged "T" attenuator that provides over 30 dB of "matched" attenuation. This device has two independent bias controls which can be adjusted to obtain the desired attenuation under matched conditions. The AT006N3-10 is the gullwing version of this device for surface mount applications.
