Covering 0.1 to 33.0 GHz, the insertion loss is less than 4 dB typical. t he attenuator bit values are 0.5 (LsB), 1, 2, 4, 8, for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at 0.3 dB typical step error with an IIP3 of +45 dBm. Five control voltage inputs, toggled between +5V and 0V, are used to select each attenuation state.
