LDB183G4510G-120

Balun Overview

The LDB183G4510G-120 is a hybrid balun from Murata Electronics designed for RF signal conditioning. It operates within a frequency range of 3.3 GHz to 3.6 GHz, with a center frequency specification of 3.45 GHz. The component provides impedance transformation between an unbalanced port and a balanced port, specified as 50 Ohms and 100 Ohms respectively. It features a maximum insertion loss of 1.35 dB. The device utilizes surface-mount technology (SMD/SMT) for board mounting and is supplied in tape and reel packaging.

Balun Feature Summary

• Provides conversion between single-ended and differential signals using hybrid balun architecture
• Supports high-frequency RF applications within the 3.3 GHz to 3.6 GHz operational band
• Facilitates impedance matching between 50 Ohm unbalanced lines and 100 Ohm balanced circuits

Balun Applications

• RF front-end modules requiring single-ended to differential signal conversion
• Wireless communication systems operating in the 3.3–3.6 GHz spectrum
• Balanced mixer or amplifier input stages needing impedance transformation

Balun Procurement Notes

Verify current availability status as this component is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm that the specific ordering suffix matches the required impedance and frequency specifications. Ensure compatibility with existing PCB layouts due to the SMD package dimensions. Review the latest datasheet for any updates regarding end-of-life timelines or recommended replacement parts before finalizing procurement plans.

Balun Selection Notes

Select this component when a compact solution is needed for converting 50 Ohm single-ended signals to 100 Ohm differential lines at frequencies around 3.45 GHz. Consider the low insertion loss characteristic for maintaining signal integrity in sensitive RF paths. Evaluate the thermal performance within the specified operating temperature range during design integration. Ensure the application does not require higher power handling capabilities than what the standard hybrid balun configuration supports.

Balun Part Context

This part belongs to the LDB series of hybrid baluns manufactured by Murata Electronics. These components are categorized under signal conditioning products within the broader filter and passive component portfolio. The series is designed to address the increasing demand for balanced architectures in modern RF transceivers, offering a compact alternative to discrete transformer-based solutions.

Balun Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the scheduled obsolescence status, engineers should initiate a design change process early. Consult official Murata channels for potential next-generation replacements or updated product line recommendations.
