LFD182G45MJ6D431

RF Multiplexers Overview

The LFD182G45MJ6D431 is a surface-mount LC diplexer manufactured by Murata Electronics. It operates with a low frequency band of 2.4GHz to 2.5GHz and a high frequency band of 4.9GHz to 5.95GHz. The component utilizes a 0603 (1608 Metric) package with a 6-pad configuration. It provides a minimum attenuation of 30.00dB in the low band and up to 20.00dB in the high band.

RF Multiplexers Feature Summary

• Integrates dual-band filtering capabilities within a compact surface-mount footprint
• Provides significant signal isolation between distinct frequency ranges
• Designed for reliable operation in space-constrained electronic assemblies

RF Multiplexers Applications

• Wireless communication modules requiring simultaneous dual-band transmission
• Mobile device RF front-end architectures
• IoT devices utilizing multiple wireless protocols

RF Multiplexers Procurement Notes

Verify that the specific suffix MJ6D431 matches the required frequency bands and attenuation specifications for the target design. Confirm compatibility with standard reflow soldering profiles for 0603 packages. Ensure the 6-pad layout aligns with the PCB footprint guidelines provided in the official datasheet to maintain electrical performance and mechanical stability.

RF Multiplexers Selection Notes

Select this component when a single integrated solution is preferred over discrete filters for dual-band applications. Consider the 0603 size constraint and the specific 6-pad requirement during layout. Evaluate the trade-off between the 30dB low-band and 20dB high-band attenuation against system noise floor requirements. This part is suitable for designs prioritizing miniaturization without sacrificing basic isolation.
