The AT002N5-00 attenuator provides up to 50 dB variable attenuation from DC3 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 A 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.
