Covering DC to 3 GHz, the insertion loss is 1.5 dB and the attenuator bit values are 0.5 (LsB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is excellent at ±0.25 dB typi- cal step error with an IIP3 of +45 dBm. six bit serial control words are used to select each attenuation state. A single Vdd bias of +5V is required. Parameter Frequency (GHz) Min. typ.
