B39321B3751U310

Overview

The B39321B3751U310 is a Surface Acoustic Wave (SAW) filter designed for RF front-end applications. It operates at a center frequency of 315MHz with a bandwidth of 620kHz. The component features an insertion loss of 2.1dB and is manufactured in an 8-SMD, no-lead surface mount package.

Feature Summary

Surface Acoustic Wave technology for signal isolation
Optimized for remote control frequency bands
Compact surface-mount construction

Applications

Remote control systems
RF signal filtering
Wireless communication interfaces

Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and pin configurations. Ensure compatibility with existing PCB footprints for 8-SMD packages. Cross-reference manufacturer documentation for any recent design changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a SAW filter is required for 315MHz applications. Consider the 620kHz bandwidth and 2.1dB insertion loss against system requirements. Evaluate the SMD package suitability for automated assembly processes and spatial constraints within the target device design.

Part Context

This part belongs to Qualcomm's RF front-end filter portfolio, which includes various discrete and embedded solutions for mobile and IoT devices. While the broader family supports 4G/5G and Wi-Fi, this specific model targets lower-frequency remote control applications rather than high-bandwidth cellular communications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify functional equivalence with other 315MHz SAW filters if substitution is necessary.
