ADRF5721BCCZN-R7

Attenuators Overview

The ADRF5721BCCZN-R7 is a silicon digital attenuator manufactured by Analog Devices Inc. It provides a 30 dB attenuation control range in 2 dB steps using a 4-bit architecture. The device operates from 9 kHz to 40 GHz with a single channel configuration. It utilizes an LGA-16 package and supports SMD/SMT installation. The component functions at a working supply voltage of 3.3 V, with an operating temperature range spanning -40 C to +105 C.

Attenuators Feature Summary

• Provides precise digital attenuation control across a wide frequency spectrum up to 40 GHz
• Features a compact LGA-16 surface-mount package for efficient PCB integration
• Operates reliably within extended industrial temperature ranges

Attenuators Applications

• Wireless communication systems requiring variable signal attenuation
• Test and measurement equipment needing precise RF signal control
• Phased array antenna beamforming networks

Attenuators Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the LGA-16 package dimensions match your board layout requirements. Ensure compatibility with 3.3 V logic levels for control signals. Check current availability status as supply may be limited or subject to factory orders. Validate RoHS compliance documentation for regulatory adherence.

Attenuators Selection Notes

Choose this component when a 30 dB range with 2 dB resolution is required. Consider the 4-bit interface simplicity against higher-resolution alternatives. Evaluate the 40 GHz upper frequency limit against system bandwidth needs. Assess the LGA-16 footprint constraints relative to other available packages. Verify thermal performance within the specified operating temperature range.

Attenuators Part Context

This part belongs to the ADRF5721 series of silicon digital attenuators. It complements other models like the ADRF5720 which offers finer 0.5 dB steps. The series targets high-frequency applications requiring robust digital control. Analog Devices designs these components for wireless infrastructure and test instruments.

Attenuators Replacement Considerations

The ADRF5720BCCZN-R7 offers similar functionality but with 6-bit resolution and 0.5 dB steps instead of 4-bit and 2 dB. Verify if the finer resolution is necessary for your application. Both parts share the same manufacturer and general operational principles.
