BDA4700

Attenuators Overview

The BDA4700 is a 7-bit Digital Step Attenuator (DSA) manufactured by BeRex Corp, designed for high-frequency attenuation control in precision wireless applications. It operates within a frequency range of 1 MHz to 8000 MHz and provides an attenuation range of 0 dB to 31.75 dB with 0.25 dB resolution steps. The device features a 50 Ohm impedance and is housed in a compact 24-VFQFN Exposed Pad package measuring 4x4 mm. It supports digital control interfaces for precise signal level management.

Attenuators Feature Summary

• Provides precise digital step attenuation control across a wide frequency spectrum
• Compact surface-mount QFN package design suitable for space-constrained layouts
• Supports high-frequency operation up to 8 GHz for modern wireless standards

Attenuators Applications

• Precision wireless communication systems requiring variable attenuation
• RF test and measurement equipment calibration
• Base station and mobile device signal conditioning

Attenuators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and electrical specifications. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Check for any specific handling instructions related to the exposed pad thermal termination during soldering. Ensure compatibility with your digital control logic levels before integration.

Attenuators Selection Notes

Select this component when a wideband attenuation range up to 8 GHz is required with fine 0.25 dB resolution steps. Consider the 24-lead QFN package for its small footprint and thermal performance. Evaluate the need for digital control interfaces versus analog alternatives based on system complexity. Verify that the 50 Ohm impedance matches your RF transmission line requirements.
