LDB183G6BAAEA059

Balun Overview

The LDB183G6BAAEA059 is an RF balun manufactured by Murata Electronics, designed for high-frequency signal conversion. It operates within a frequency range of 2.3GHz to 5GHz. The component provides impedance transformation between unbalanced and balanced lines, specifically converting between 50 Ohm and 100 Ohm impedances. It is housed in a compact 0603 (1608 Metric) surface-mount package featuring six printed circuit board pads. This configuration supports efficient integration into space-constrained electronic designs requiring reliable RF performance.

Balun Feature Summary

• Converts single-ended signals to differential signals across specified microwave frequencies
• Matches 50 Ohm unbalanced ports to 100 Ohm balanced ports for impedance alignment
• Utilizes a miniature 0603 footprint with six contact pads for SMT assembly

Balun Applications

• Wireless communication modules
• RF front-end circuits
• Balanced antenna interfaces

Balun Procurement Notes

Verify the current lifecycle status before procurement, as distributor records indicate this specific part may be scheduled for obsolescence or discontinuation by the manufacturer. Confirm availability through official channels and check for valid datasheets. Ensure the ordering suffix matches the required specifications exactly, as variations may exist within the product family. Cross-reference with authorized distributors to confirm authenticity and compliance with RoHS standards.

Balun Selection Notes

Select this component when a 2.3GHz to 5GHz operating range is required for RF balun applications. The 50/100 Ohm impedance ratio suits specific balanced line requirements. The 0603 package size is appropriate for dense PCB layouts. Evaluate alternative models like the LDB184 series if the application requires a higher frequency range extending up to 6GHz. Ensure the design accommodates the six-pad footprint geometry.

Balun Part Context

This component belongs to the LDB series of LC baluns from Murata Electronics. These devices are engineered for radio frequency applications, providing compact solutions for signal balancing. The series typically utilizes lumped element LC topologies to achieve wideband performance in small form factors. This specific model targets the lower end of the UWB spectrum compared to other variants in the lineup.

Balun Replacement Considerations

Public data identifies the LDB184G6BAAEA048 as a related variant. This substitute offers a frequency range of 3.2GHz to 6GHz with identical 50/100 Ohm impedance and 0603 packaging. Verify that the shifted frequency response aligns with the target application requirements before substitution.
