LFD21829MDPFC270

RF Multiplexers Overview

The LFD21829MDPFC270 is an RF diplexer manufactured by Murata Electronics, designed for signal conditioning applications. It operates within frequency ranges of 698 MHz to 960 MHz and 1.71 GHz to 2.69 GHz. The component features a maximum high-band insertion loss of 0.55 dB at 25°C and supports a power handling capacity of 3 W. It is housed in an 0805 (2012 Metric) surface-mount package with six pad connections. The device functions reliably across an operating temperature range of -40°C to +85°C.

RF Multiplexers Feature Summary

• Integrates dual frequency band filtering into a single compact surface-mount package
• Provides low insertion loss characteristics for efficient signal transmission
• Supports high power handling capabilities suitable for active antenna systems

RF Multiplexers Applications

• LTE mobile communication devices
• Active antenna units (AAU)
• Small cell base station infrastructure
• RF front-end modules requiring duplexing

RF Multiplexers Procurement Notes

Verify the specific ordering suffix and tape-and-reel specifications directly with Murata Electronics or authorized distributors before procurement. Confirm that the component meets all required environmental certifications and RoHS compliance standards for your target market. Ensure that the 0805 footprint matches your PCB design guidelines and soldering process capabilities to prevent assembly defects.

RF Multiplexers Selection Notes

Select this component when designing circuits requiring simultaneous operation in sub-1 GHz and 2 GHz bands within a limited board area. Evaluate the 3 W power rating against peak envelope power requirements to ensure reliability. Consider the 0.55 dB insertion loss impact on overall system gain and noise figure during link budget calculations.

RF Multiplexers Part Context

This part belongs to Murata's LFD series of LC duplexers, which utilize multilayer ceramic technology. These components are engineered to combine transmit and receive paths efficiently, reducing the need for external switching components. The series is widely used in modern wireless infrastructure to minimize size while maintaining high performance in demanding RF environments.
