Introduction

The HMC1019ALP4E 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 4.0 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8 for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.3 dB typical step error with an IIP3 of +45 dBm. The control interface is CMOS/TTL compatible and accepts a three wire serial input. The HMC1019ALP4E features a user selectable power up state and a serial output port for cascading other Analog Devices serial controlled components.
