FAR-D5NG-881M50-M11Z-Z

RF Multiplexers Overview

The FAR-D5NG-881M50-M11Z-Z is a Surface Acoustic Wave (SAW) duplexer manufactured by Taiyo Yuden. It operates at a center frequency of 881.5 MHz and features a 9-SMD, no-lead surface mount package. The component exhibits an insertion loss of 1.45 dB. It is designed for RF signal conditioning in wireless communication systems. The device complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) rating of 1, indicating unlimited floor life. The part status is Not Recommended for New Designs (NRND).

RF Multiplexers Feature Summary

• Utilizes Surface Acoustic Wave (SAW) technology for efficient signal filtering.
• Provides integrated transmit and receive path isolation within a single compact module.
• Supports surface mount assembly via a leadless SMD footprint.

RF Multiplexers Applications

• RF signal conditioning in mobile communication devices
• Wireless transceiver modules requiring band-specific duplexing
• Base station or access point front-end circuits

RF Multiplexers Procurement Notes

Verify the current lifecycle status before procurement, as this component is designated as Not Recommended for New Designs (NRND). Confirm that existing inventory meets project requirements without necessitating future redesigns. Ensure compatibility with existing PCB layouts and soldering profiles. Check for any pending Product Change Notifications (PCNs) that may affect specifications or availability. Validate supply chain stability to mitigate risks associated with end-of-life components.

RF Multiplexers Selection Notes

Select this component only if the specific 881.5 MHz operating frequency aligns precisely with system requirements. Consider the NRND status when planning long-term production runs, as future availability may be limited. Evaluate the 1.45 dB insertion loss against system link budget constraints. Verify that the 9-SMD package dimensions fit within the allocated board space. Assess alternative parts if new design implementation is required to ensure long-term supply security.

RF Multiplexers Part Context

This part belongs to the D5 series of SAW duplexers from Taiyo Yuden, targeting specific cellular or wireless bands around 800-900 MHz. It serves as a passive RF filter component essential for separating transmit and receive signals in dual-band or multi-mode radio frequency front ends. The device represents a mature technology solution for established communication protocols.

RF Multiplexers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, engineers should identify equivalent components from other manufacturers or newer generations within the same family that offer updated lifecycle support and comparable electrical characteristics.
