HMC8073LP3DE

HMC8073LP3DE is a 6bit silicon digital step attenuator. It 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 operating temperature range. The radio frequency (RF) input and output are internally matched to 50 ohm 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 application includes cellular infrastructure, microwave radios, very small aperture terminals, test equipment and sensors.
