Description
The AT002N5-00 attenuator provides up to 50 dB variable
attenuation from DC–3 GHz under non-reflective
conditions. Attenuation can be controlled by varying each
of the two control bias voltages from 0 to -5 V. The control
current is less than 100 µA and the attenuator will operate
at 0 dBm with switching time, typically 10 ns. The chip is
configured using two “T” attenuators in the series and two
in parallel. This device may be used with a single bias
(V1 = 0) but with reduced attenuation and match.
Applications include fast response AGC circuits requiring
high attenuation, such as for radar processing,
instrumentation, and levelers in RF equipment.
