Covering 0.1 to 30.0 GHz, the insertion loss is less than 5.5 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. The control interface is CMOS/TTL compatible and accepts a three wire serial input. The HMC1018ALP4E features a user selectable power up state and a serial-output port for cascading other Hittite serial controlled components. im in ar Functional Diagram Pr el Attenuators - Digital - SMT 1.0 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.1 - 30 GHz Electrical Specifications, TA = +25° C, With Vdd = Vdd1 = +5V, Vss = -5V Parameter Typ.
