B39881B9446K610

Overview

The B39881B9446K610 is a Surface Acoustic Wave (SAW) filter manufactured by Qualcomm. It operates at a center frequency of 942.5 MHz for the low band and 1843.0 MHz for the high band. The component utilizes a 10-SMD, no-lead package designed for surface mount installation. This device functions as a duplexer within RF front-end architectures, providing necessary signal isolation between transmit and receive paths in wireless communication systems.

Feature Summary

• Integrates dual-band filtering capabilities for distinct low and high frequency operations
• Utilizes Surface Acoustic Wave technology for efficient RF signal processing
• Designed for compact surface-mount integration into mobile and IoT hardware

Applications

• Mobile communication devices requiring dual-band support
• Internet of Things (IoT) modules
• Wireless infrastructure components

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variations such as tape-and-reel options if available. Ensure the obsolete status does not impact long-term supply chain stability for production needs.

Selection Notes

Select this component when designing systems requiring SAW-based duplexing for the specified frequency bands. Evaluate compatibility with existing PCB layouts due to the 10-SMD footprint. Consider thermal management requirements and ensure the device meets the electromagnetic interference standards relevant to the target application environment.
