SF2287E

Overview

The SF2287E is a surface acoustic wave (SAW) bandpass filter manufactured by RFMi. It operates with a center frequency of 895 MHz and supports a bandwidth ranging from 894 MHz to 896 MHz. The component features a typical insertion loss of 2.6 dB and maintains a system impedance of 50 Ohms. It is rated for a voltage of 5 V and utilizes an SM-3030-6 package configuration. This signal conditioning device is designed for board mount applications using SMD/SMT termination types.

Feature Summary

• Utilizes surface acoustic wave technology for precise signal filtering
• Provides defined bandpass characteristics centered at 895 MHz
• Designed for low insertion loss performance in RF circuits

Applications

• Wireless communication systems requiring 895 MHz filtering
• RF signal conditioning modules
• General purpose RF SAW filter applications

Procurement Notes

Verify the specific datasheet version and electrical tolerances against your design requirements before procurement. Confirm that the 5 V rating and 50 Ohm impedance align with your circuit specifications. Ensure compatibility with the SM-3030-6 footprint during PCB layout. Check for any RoHS compliance documentation if required by your manufacturing standards. Validate the operating temperature range against your environmental conditions.

Selection Notes

Select this component when a narrowband SAW filter is needed around the 895 MHz frequency. Consider the 2.6 dB insertion loss impact on overall system gain. The 50 Ohm impedance matches standard RF transmission lines. Evaluate the physical size constraints relative to the SM-3030-6 package dimensions. Compare performance metrics against alternative SAW filters if stricter loss or bandwidth specifications are necessary.
