LFD21829MDKED859

RF Multiplexers Overview

The LFD21829MDKED859 is an RF diplexer manufactured by Murata Electronics, designed for signal conditioning applications. It operates with a nominal impedance of 50 Ohms and supports a maximum power capacity of 1W. The device features two distinct frequency bands: one spanning from 698MHz to 960MHz and the other from 1.71GHz to 2.69GHz. It is housed in an 0805 (2012 Metric) surface-mount package with six pad connections. The component is rated for operation within a temperature range of -40°C to +85°C.

RF Multiplexers Feature Summary

RF Multiplexers Procurement Notes

Verify the specific ordering suffix against official Murata documentation to ensure correct band specifications and tolerance levels. Confirm that the 0805 package dimensions align with your PCB layout requirements. Check for any recent product lifecycle notifications or obsolescence warnings directly from the manufacturer before finalizing procurement plans.

RF Multiplexers Selection Notes

Select this component when designing circuits requiring simultaneous handling of sub-1GHz and higher frequency bands within a constrained space. Ensure the system's expected power levels remain within the 1W limit to maintain performance integrity. Verify that the operating temperature environment falls within the specified -40°C to +85°C range for reliable long-term operation.

RF Multiplexers Part Context

This part belongs to Murata's LFD series of LC diplexers, which are engineered for noise suppression and signal separation in RF applications. The series utilizes thin-film technology to achieve precise frequency characteristics in small form factors, catering to the miniaturization demands of modern electronic devices.

RF Multiplexers Replacement Considerations

Consult official Murata cross-reference lists for verified substitutes. Generic equivalents may not match the specific insertion loss or isolation characteristics required for critical RF paths.
