ADRF5700BCCZN

Attenuators Overview

The ADRF5700BCCZN is a silicon-based, 5-bit digital attenuator manufactured by Analog Devices Inc. It provides a total attenuation control range of 46 dB with resolution in 2 dB steps. The device operates across a frequency range from 100 MHz to 22 GHz and features a 50 Ohm impedance. It utilizes a 20-VFLGA package with an exposed pad for surface mount installation.

Attenuators Feature Summary

• Provides precise digital attenuation control with 5-bit resolution
• Operates at high frequencies up to 22 GHz
• Designed for direct interface with digital control logic

Attenuators Applications

• RF signal path management in wireless communication systems
• Test and measurement equipment requiring variable attenuation
• Phased array antenna beamforming networks

Attenuators Procurement Notes

Verify the specific suffix BCCZN against the official Analog Devices datasheet to confirm pinout and package dimensions. Ensure compatibility with the intended PCB layout for the 20-VFLGA exposed pad thermal requirements. Confirm that the operating voltage levels match the digital control interface specifications provided in the electrical characteristics table.

Attenuators Selection Notes

Select this component when a wide bandwidth extending to 22 GHz is required alongside fine 2 dB step resolution. Consider the 46 dB dynamic range for applications needing significant signal adjustment. Evaluate the thermal performance of the VFLGA package relative to the expected power dissipation in the target application environment.

Attenuators Part Context

This part belongs to the ADRF5700 series of silicon digital attenuators. It is designed for high-frequency RF applications where compact size and digital control are prioritized. The series typically includes variants optimized for different frequency ranges and attenuation resolutions within the Analog Devices portfolio.

Attenuators Replacement Considerations

Check for ADRF5700 variants with different suffixes or packages if supply constraints exist. Verify that any substitute maintains the 22 GHz upper frequency limit and 5-bit resolution. Cross-reference the pinout and thermal pad configuration to ensure mechanical and electrical compatibility.
