DXW21BN7511TL

Balun Overview

The DXW21BN7511TL is a surface-mount balun transformer from Murata Electronics, designed for RF signal conditioning. It operates within a frequency range of 50 MHz to 870 MHz and features a 1:1 turns ratio. The component provides impedance transformation between unbalanced and balanced lines, both rated at 75 ohms. It exhibits a maximum insertion loss of 1 dB. The device is housed in a compact 0805 (2012 metric) package with dimensions of 2 mm x 1.2 mm x 1.2 mm. It supports a minimum operating temperature of -40°C and a maximum of 85°C, complying with RoHS3 standards.

Balun Feature Summary

• Converts single-ended signals to differential signals for balanced transmission lines
• Maintains signal integrity through low insertion loss characteristics
• Facilitates direct integration into compact surface-mount PCB layouts

Balun Applications

• RF front-end circuits requiring 75-ohm impedance matching
• Wireless communication systems operating in the VHF/UHF bands
• Signal conditioning stages for video or data transmission interfaces

Balun Procurement Notes

Verify the specific suffix TL against official Murata documentation to confirm reel packaging specifications and tape-and-reel parameters. Ensure that the ordered part number matches the required frequency range and impedance values precisely. Cross-reference the manufacturer's latest datasheet for any updates on compliance status or recommended soldering profiles prior to procurement.

Balun Selection Notes

Select this component when a 75-ohm to 75-ohm balun conversion is required within the 50 MHz to 870 MHz spectrum. Consider the 0805 footprint constraints and the thermal operating limits of -40°C to 85°C during design. Evaluate the 1 dB insertion loss specification against system budget requirements to ensure adequate signal performance.
