Covering 0.4 to 6 GHz, the insertion loss is typically less than 1.6 dB. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.25 dB typical with an IIP3 of up to +52 dBm. Five bit serial control words are used to select each attenuation state. A single Vcc bias of +3.3V to +5V is required. Electrical Specifications, TA = +25° C, Vcc = +3.3V to +5V Parameter Typical Max.
