SF2149A

Overview

The Murata Electronics SF2149A is a Surface Acoustic Wave (SAW) filter designed for RF signal conditioning. It operates at a center frequency of 46.08 MHz with a bandwidth of 5 MHz and an insertion loss of 8 dB. The component utilizes a 12-SMD, no-lead package suitable for surface mount technology. It is specified for cellular and SCDA applications, providing precise frequency selection in communication systems.

Feature Summary

• Surface Acoustic Wave (SAW) technology for efficient RF filtering
• Optimized for cellular and SCDA communication bands
• Compact 12-SMD leadless package design

Applications

• Cellular radio frequency front ends

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before integration, as manufacturing processes may evolve. Confirm that the 12-SMD package dimensions align with your PCB footprint requirements. Ensure compatibility with your assembly equipment for small outline components. Check for any recent product change notices regarding material composition or performance tolerances to maintain supply chain integrity.

Selection Notes

Select this component when a 46.08 MHz center frequency with 5 MHz bandwidth is required for cellular or SCDA applications. The 8 dB insertion loss should be evaluated against system link budget constraints. Consider the 12-SMD form factor for space-constrained designs requiring robust surface mounting without traditional leads.
