Covering. GHz to 8. GHz, the insertion loss is less than. db typical. The attenuator bit values are. (LSB),,,, 8, and for a total attenuation of. Attenuation accuracy is excellent at ±. db typical step error with an IIP3 of +m. Six control voltage inputs, toggled between and +3 to +V, are used to select each attenuation state. A single VDD bias of +3 to +V is required. Electrical Specifications T A = + C, With VDD = +V & VCTL= /+V (Unless Otherwise Noted) Insertion Loss Parameter Frequency Min. Typ. Max.
