LDB21906M20C-001

Balun Overview

The LDB21906M20C-001 is a multi-layer hybrid balun manufactured by Murata Electronics, designed for surface-mount applications in the 0805 (2012 Metric) package. It operates within an RF frequency range of 887 MHz to 925 MHz. The component provides impedance transformation between unbalanced and balanced ports, rated at 50 Ohms and 200 Ohms respectively. Key electrical specifications include a maximum insertion loss of 1.3 dB. This device is intended for use in wireless communication systems requiring signal balancing.

Balun Feature Summary

• Multi-layer hybrid construction for compact integration
• Balanced-to-unbalanced signal conversion capability
• Surface-mount design suitable for automated assembly

Balun Applications

• Wireless communication modules
• RF front-end circuits
• Signal processing systems

Balun Procurement Notes

Verify that the received components match the Murata Electronics part number LDB21906M20C-001 exactly. Confirm the package type is 0805 and the operating frequency range aligns with 887 MHz to 925 MHz. Ensure documentation confirms RoHS compliance and check for any specific handling requirements related to surface-mount baluns during procurement.

Balun Selection Notes

Select this component when a 50 Ohm to 200 Ohm impedance transformation is required in the 887-925 MHz band. The choice depends on the need for a low-profile 0805 footprint and specific insertion loss characteristics not exceeding 1.3 dB. Consider thermal and mechanical constraints associated with multi-layer hybrid devices in dense PCB layouts.

Balun Part Context

This balun belongs to Murata's family of passive RF components, specifically designed for high-frequency signal integrity. It complements other RF filters and inductors by providing necessary phase and amplitude balance for differential signaling architectures in modern electronic devices.

Balun Replacement Considerations

No direct substitute part numbers are publicly confirmed for this specific model. Cross-referencing requires matching the 50/200 Ohm impedance ratio, 0805 package dimensions, and 887-925 MHz operational bandwidth.
