Part details & applications

The HMC1018ALP4E is a broadband 5-bit GaAs IC digital attenuator in a low cost leadless surface mount package. Covering 0.1 to 30.0 GHz, the insertion loss is less than 5.5 dB typical. The attenuator bit values are 1.0 (LS B), 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 Analog Devices serial controlled components.
