ADRF5731BCCZN-R7

Attenuators Overview

The ADRF5731BCCZN-R7 is a silicon-based, digitally controlled 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 features a 4-bit resolution and operates as a single-channel component. Its operational frequency range spans from 100 MHz to 40 GHz, supporting a system impedance of 50 Ohms. The unit is housed in a compact LGA-16 package and requires a 3.3 V power supply. It is designed for surface mount installation and functions within a temperature range of -40°C to +105°C.

Attenuators Feature Summary

• Digital control interface enabling precise attenuation adjustment
• Wideband operation extending up to 40 GHz
• Compact leadless chip carrier packaging for space-constrained designs

Attenuators Applications

• Phased array radar systems
• Electronic warfare equipment
• Satellite communication terminals

Attenuators Procurement Notes

Verify the specific suffix R7 against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with standard SMD/SMT assembly processes. Confirm that the LGA-16 package dimensions align with the target PCB footprint. Validate thermal management requirements for the specified operating temperature range.

Attenuators Selection Notes

Select this component when high-frequency digital attenuation is required up to 40 GHz. Consider the 2 dB step resolution for applications needing coarse-to-moderate signal level control. Evaluate the 30 dB maximum range against system dynamic requirements. Assess the 3.3 V supply constraint relative to available logic levels.

Attenuators Part Context

This part belongs to the ADRF5731 series of silicon digital attenuators. It is distinct from other series members like the ADRF5716 or ADRF5720 by its specific 4-bit architecture and 2 dB LSB configuration. The series targets high-performance RF applications requiring reliable digital control over wide bandwidths.

Attenuators Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinout and electrical parameters before considering any generic replacements.
