ADRF5731BCCZN

Attenuators Overview

The ADRF5731BCCZN is a silicon, 4-bit digital attenuator manufactured by Analog Devices Inc. It provides a total attenuation control range of 30 dB with a least significant bit (LSB) step size of 2 dB. The device operates over a frequency range from 100 MHz to 40 GHz and features a 50 Ohm impedance. It is housed in a 16-lead Very Thin Fine-Pitch Leadless Grid Array (VFLGA) package with an exposed pad. The component supports single-supply operation at 3.3 V and is designed for high-linearity RF applications.

Attenuators Feature Summary

• Provides precise digital attenuation control with 2 dB steps across a 30 dB range
• Operates effectively up to 40 GHz for wideband signal processing
• Utilizes a compact 16-lead VFLGA package for space-constrained designs

Attenuators Applications

• Wireless infrastructure base stations
• Point-to-point microwave radio systems
• Test and measurement equipment requiring high-frequency attenuation

Attenuators Procurement Notes

Verify the specific suffix (e.g., -R7 for reel packaging) against your assembly requirements. Confirm availability status as supply may be limited. Ensure compatibility with 3.3 V logic levels for control signals. Check RoHS compliance documentation for regulatory adherence. Validate thermal performance within the specified operating temperature range.

Attenuators Selection Notes

Select this component when a wide bandwidth extending to 40 GHz is required. Choose the 4-bit resolution if coarse attenuation steps are sufficient for the application. Consider the VFLGA package constraints during PCB layout. Evaluate insertion loss specifications relative to system noise budget requirements.

Attenuators Part Context

This part belongs to the ADRF5731 series of silicon digital attenuators. It shares functional similarities with other members like the ADRF5720 but differs in bit resolution and step size. The series targets high-performance RF front-end modules requiring reliable attenuation control.

Attenuators Replacement Considerations

Direct substitutes include the ADRF5731BCCZN-R7 variant which offers identical electrical characteristics but in tape-and-reel packaging. Verify pinout and thermal pad configurations match before substitution.
