LFD182G45PJ2F489

RF Multiplexers Overview

The Murata LFD182G45PJ2F489 is a chip multilayer diplexer designed for RF applications. It operates with a low band of 2.4GHz to 2.5GHz and a high band of 5.17GHz to 7.125GHz. The component features a nominal impedance of 50Ω and supports a maximum power capacity of 1W. It is housed in a compact 0603 (1608 Metric) surface-mount package with six PCB pads, measuring 1.60mm x 0.80mm.

RF Multiplexers Feature Summary

• Dual-band operation supporting Wi-Fi and ISM frequency ranges
• Compact 0603 surface-mount footprint for space-constrained designs
• Integrated multiplexing functionality within a single passive component

RF Multiplexers Applications

• Wireless LAN modules requiring simultaneous 2.4GHz and 5GHz transmission
• IoT devices utilizing dual-band connectivity
• Mobile communication terminals integrating multiple RF standards

RF Multiplexers Procurement Notes

Verify the specific datasheet version to confirm attenuation characteristics and insertion loss values, as these parameters are critical for system performance. Ensure that the 0603 footprint matches the target PCB layout exactly. Confirm RoHS compliance status if required by regional regulations. Cross-reference the pinout diagram during schematic capture to prevent signal path errors.

RF Multiplexers Selection Notes

Select this component when a single solution is needed to separate or combine signals across the specified 2.4GHz and 5.17-7.125GHz bands. Consider the 1W power handling limit against the transmitter output levels. The 50Ω impedance must align with the surrounding RF trace design. Evaluate the thermal requirements of the application against the component's physical size.

RF Multiplexers Part Context

This part belongs to Murata's LFD series of chip multilayer diplexers. These components utilize advanced ceramic technology to achieve high selectivity in small packages. The series is engineered for modern wireless standards, offering integration benefits over discrete filter solutions. It complements other RF front-end components like baluns and bandpass filters.

RF Multiplexers Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Alternative selection requires matching the dual-band frequency specifications, 50Ω impedance, and 0603 package dimensions. Consult manufacturer catalogs for comparable diplexers with similar passband and stopband requirements.
