LFD212G45DP3A188

Overview

The Murata LFD212G45DP3A188 is a Surface Acoustic Wave (SAW) diplexer designed for signal conditioning in RF applications. It operates with two distinct frequency bands: a primary band centered at 2.45 GHz and a secondary band centered at 5.375 GHz. The device supports a bandwidth of 100 MHz for the lower frequency range and 950 MHz for the higher frequency range. It is housed in an 0805 (2012 Metric) surface mount package, measuring 0.079 inches in length by 0.049 inches in width, with a maximum height of 0.039 inches (1.00 mm). The component utilizes an 8-pad configuration for mounting.

Feature Summary

• Dual-band SAW diplexer architecture enabling simultaneous operation across 2.45 GHz and 5.375 GHz frequencies
• Compact 0805 surface mount footprint optimized for high-density PCB layouts
• Integrated signal conditioning capabilities for RF path isolation

Applications

• Wireless communication systems requiring dual-frequency support
• RF front-end modules for IoT devices

Procurement Notes

Verify the specific ordering suffix DP3A188 to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free requirements against current manufacturing standards. Cross-reference the part number with official Murata documentation to validate pinout compatibility and thermal characteristics before integration into final designs.

Selection Notes

Select this component when dual-band filtering is required within a constrained 0805 footprint. Ensure the application demands the specific 2.45 GHz and 5.375 GHz center frequencies with the associated 100 MHz and 950 MHz bandwidths. Evaluate insertion loss and isolation performance against system requirements using the official datasheet electrical specifications.

Part Context

This part belongs to Murata's SAW diplexer family, specifically engineered for RF signal conditioning. It serves as a passive component for separating or combining signals in multi-band wireless environments. The device is manufactured by Murata Manufacturing Co., Ltd., leveraging established thin-film bulk acoustic resonator technology principles adapted for diplexer functions.

Replacement Considerations

Consult official Murata substitution guides for compatible alternatives. Verify that any substitute maintains identical center frequencies, bandwidths, and package dimensions. Ensure electrical performance metrics match the original design requirements without modification.
