LFD212G45DS3D345

RF Multiplexers Overview

The LFD212G45DS3D345 is an RF diplexer manufactured by Murata Electronics, designed for dual-band signal separation. It operates across two distinct frequency ranges: 2.4 GHz to 2.5 GHz and 5.15 GHz to 5.85 GHz. The component utilizes a surface-mount technology (SMT) package with dimensions of 2 mm x 1.25 mm x 1 mm, corresponding to the 0805 (2012 Metric) footprint. It features six pad connections for board integration and maintains a standard 50-ohm impedance characteristic suitable for wireless communication systems.

RF Multiplexers Feature Summary

• Dual-band frequency separation capability for 2.4 GHz and 5.15–5.85 GHz bands
• Compact surface-mount design compatible with automated assembly processes
• Standard 50-ohm impedance matching for RF circuit integration

RF Multiplexers Applications

• Wi-Fi module signal routing
• Bluetooth transceiver front-end isolation
• Dual-band wireless communication devices

RF Multiplexers Procurement Notes

Verify the specific suffix DS3D345 against official Murata documentation to confirm exact electrical tolerances and tape-and-reel specifications. Ensure compatibility with 0805 footprint soldering profiles. Cross-reference with current distributor catalogs to confirm availability status, as electronic components may undergo lifecycle changes or obsolescence notifications without immediate public announcement.

RF Multiplexers Selection Notes

Select this component when simultaneous operation in the 2.4 GHz ISM band and the 5 GHz UNII band is required within a single channel path. The small 0805 form factor makes it suitable for space-constrained mobile and IoT applications. Confirm that the insertion loss and isolation requirements of the system design align with the datasheet specifications before finalizing the bill of materials.
