BDA4710

Attenuators Overview

The BDA4710 is a 7-bit digital step attenuator manufactured by BeRex Corp, designed for high-frequency applications. It operates within a frequency range of 1 MHz to 8 GHz and features an attenuation range of 31.5 dB with a step size of 0.25 dB. The device utilizes an addressable control interface and maintains a 50-ohm impedance. It is housed in a compact 32-lead QFN package measuring 5x5x0.9 mm, suitable for surface-mount technology.

Attenuators Feature Summary

• 7-bit digital step attenuation with addressable control interface
• Wide operating frequency range from 1 MHz to 8 GHz
• Compact 32-lead QFN package for space-efficient designs

Attenuators Applications

• RF test and measurement equipment
• Wireless communication systems
• Automotive radar systems

Attenuators Procurement Notes

Verify the specific suffix or variant (e.g., BDA4710V) against project requirements, as lead times may vary. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the supplier provides official datasheets matching the exact part number to avoid compatibility issues with existing circuit designs.

Attenuators Selection Notes

Select this component when precise digital attenuation control is required across a broad microwave frequency spectrum. The addressable feature simplifies system integration compared to parallel control lines. Consider the 32-lead QFN footprint for PCB layout constraints and thermal management needs in dense electronic assemblies.

Attenuators Part Context

The BDA4710 belongs to BeRex's BDA series of digital step attenuators, which also includes models like the BDA4700 and BDA4601. These components are engineered for RF signal processing tasks requiring accurate gain adjustment. The series supports various packaging options to accommodate different board space and performance specifications.

Attenuators Replacement Considerations

The BDA4710V is a documented variant within the same product family. Verify pinout compatibility and electrical specifications before substitution. Other models in the BDA series may offer different bit resolutions or package sizes but might not match the exact frequency or control interface requirements.
