Covering 0.1 to 33.0 ghz, the insertion loss is less than 5 dB typical. the attenuator bit values are 1.0 (lsB), 2, 4, 8, 16 for a total attenuation of 31 dB. Attenuation accuracy is excellent at ±0.4 dB typical step error with an iip3 of +43 dBm. Five control voltage inputs, toggled between +5V and 0V, are used to select each attenuation state.
