SF2249E

Overview

The RFMi SF2249E is a Surface Acoustic Wave (SAW) bandpass filter designed for signal conditioning applications. It operates at a center frequency of 1.602 GHz with a bandwidth of 61 MHz, covering a range from 1.596 GHz to 1.607 GHz. The component features a 50 Ohm impedance and a voltage rating of 3 V. It is housed in an 8-SMD package with SMD/SMT termination type. This device is part of the SF series and is intended for board mount installation.

Feature Summary

• Surface Acoustic Wave technology for efficient signal filtering
• Bandpass configuration optimized for specific frequency ranges
• Compact surface-mount design for automated assembly

Applications

• General purpose RF signal processing
• Wireless communication systems requiring 1.6 GHz filtering
• Mobile device front-end modules

Procurement Notes

Verify the manufacturer designation as Akoustis- RFMi or RFMi depending on the supply channel. Confirm the package type is 8-SMD and the RoHS status is lead-free. Ensure the center frequency matches the 1.602 GHz requirement for your specific circuit design before ordering.

Selection Notes

Select this component when a SAW filter with a 61 MHz bandwidth at 1.602 GHz is required. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the 8-SMD package size for PCB layout constraints and verify the 3 V voltage rating meets system operating conditions.
