Covering DC to 13 GHz, the insertion loss is less then 4 dB typical. The atten- uator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenua- tion accuracy is excellent at ± 0.5 dB typical step error with an IIP3 of +32 dBm. Six control voltage inputs, toggled between 0 and -5V, are used to select each attenuation state. A single Vee bias of -5V allows operation at frequencies down to DC. 9 - 92 Electrical Speciﬁcations, TA = +25° C, With Vee = -5V & VCTL= 0/-5V Parameter Frequency (GHz) Min. Typ. Max.
