Description

The HMC8073 is a 6-bit digital step attenuator (DSA), operating from 0.6 GHz to 3.0 GHz, that features 31.5 dB of attenuation range with 0.5 dB steps.The HMC8073 is implemented in a silicon process, offering a fast settling time, low power consumption, and high electrostatic discharge (ESD) robustness. The device features safe state transitions, allowing attenuation state changes without overshooting, and is optimized for excellent step accuracy and high power and high linearity over frequency and temperature range. The radio frequency (RF) input and output are internally matched to 50 ? and do not require any external matching components. The design is bidirectional, and the RF input and output are interchangeable.The external address feature of the HMC8073 allows users to control up to eight DSAs using a single bus. The DSA has an on-chip regulator that supports a wide supply operating range from 3.3 V to 5.0 V with no performance change in electrical characteristics. The HMC8073 incorporates a complementary metal-oxide semiconductor (CMOS)- and transistor transitory logic (TTL)- compatible interface that supports serial (3-wire) control of the attenuator.The HMC8073 comes in an RoHS compliant, compact, 3 mm ? 3 mm LFCSP package.Applications Cellular infrastructure Microwave radios? Very small aperture terminals Test equipment and sensors
