ADRF5721BCCZN

Attenuators Overview

The ADRF5721BCCZN is a silicon-based digital attenuator manufactured by Analog Devices Inc. It features a 4-bit control interface providing a total attenuation range of 30 dB in discrete 2 dB steps. The device operates across a frequency spectrum from 9 kHz to 40 GHz, supporting high-frequency applications. It utilizes an LGA-16 package and functions with a single supply voltage. Key electrical parameters include a maximum attenuation of 30 dB and a step size of 2 dB.

Attenuators Feature Summary

• Provides precise digital attenuation control with 4-bit resolution
• Operates effectively across ultra-wideband frequencies up to 40 GHz
• Utilizes a compact LGA-16 surface-mount package for integration

Attenuators Applications

• Wireless communication systems requiring variable gain control
• Test and measurement equipment calibration circuits
• RF front-end modules in base station architectures

Attenuators Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and lot traceability prior to acquisition. Ensure storage conditions meet humidity sensitivity requirements to prevent package degradation during handling and assembly processes.

Attenuators Selection Notes

Select this component when wideband operation up to 40 GHz is required with coarse 2 dB step resolution. Consider the LGA-16 footprint for PCB layout constraints. Evaluate thermal dissipation capabilities within the target operating temperature range of -40 C to +105 C for system reliability.

Attenuators Part Context

This part belongs to the ADRF series of radio frequency integrated circuits designed for high-performance wireless infrastructure. It complements other attenuators like the ADRF5720 by offering different bit resolutions and step sizes, allowing designers to balance precision against complexity in signal chain management.

Attenuators Replacement Considerations

The ADRF5721BCCZN-R7 is a reel-packaged variant of the same functional device. Verify pinout compatibility and package dimensions before substituting. Ensure that the specific suffix does not alter electrical characteristics or operational specifications.
