LFD182G45MJ5E355

RF Multiplexers Overview

The LFD182G45MJ5E355 is an RF diplexer manufactured by Murata Electronics, designed for dual-band WLAN applications. It operates at center frequencies of 2.45 GHz and 5.425 GHz with respective bandwidths of 2.4–2.5 GHz and 4.9–5.95 GHz. The device features low insertion loss, specified as a maximum of 0.40 dB at 25°C and 0.50 dB across the -40°C to +85°C temperature range for the lower band. It supports a permissible power of 3W and maintains a VSWR of 1.50 maximum. Packaged in a compact 0603 (1608 Metric) surface-mount footprint measuring 1.60mm x 0.80mm x 0.70mm.

RF Multiplexers Procurement Notes

Verify component authenticity through authorized Murata distributors or certified supply chain partners. Confirm that the received parts match the specific ordering suffix MJ5E355 to ensure correct frequency specifications and packaging configuration. Request original manufacturer documentation or test reports to validate compliance with RoHS standards and moisture sensitivity level requirements prior to integration into production lines.

RF Multiplexers Selection Notes

Select this component when a single solution is required to separate transmit and receive paths for both 2.4GHz and 5GHz bands within a limited board area. The 0603 package size offers a balance between electrical performance and footprint efficiency compared to larger discrete filter assemblies. Ensure the system's power handling requirements do not exceed the 3W permissible limit during peak operation conditions.

RF Multiplexers Part Context

This part belongs to Murata’s LFD series of LC diplexers, which are engineered for high-frequency signal conditioning. The LFD182G45 series specifically targets WLAN environments, providing isolation between closely spaced frequency bands. These components utilize internal LC resonator structures to achieve sharp cutoff characteristics without external tuning, simplifying the RF front-end design for modern wireless communication devices.

RF Multiplexers Replacement Considerations

Direct substitutes must maintain identical center frequencies (2.45GHz/5.425GHz), bandwidths, and 0603 footprints. Verify that alternative diplexers offer comparable insertion loss and VSWR specifications to prevent signal degradation. Cross-reference pinout configurations and thermal ratings to ensure compatibility with existing PCB layouts and operational temperature ranges.
