SF2271C

Overview

The SF2271C is a Surface Acoustic Wave (SAW) filter designed for signal conditioning applications. It operates at a center frequency of 460 MHz with a bandwidth of 23.4 MHz, covering the range from 459.2 to 461.2 MHz. The device features a nominal impedance of 50 Ohms and supports a maximum voltage rating of 3 V. It exhibits an insertion loss of 1.5 dB and is available in a surface-mount package.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF signal filtering
• Provides high selectivity with a defined 23.4 MHz bandwidth around the 460 MHz center frequency
• Designed for low insertion loss to maintain signal integrity in signal conditioning circuits

Applications

• General purpose RF signal conditioning
• Wireless communication systems requiring 460 MHz band filtering
• RF front-end modules

Procurement Notes

Verify the specific package variant and lead times directly with authorized distributors or the manufacturer. Confirm that the 3 V rating and 50 Ohm impedance align with your circuit design requirements before ordering. Ensure compatibility with standard SMD/SMT assembly processes.

Selection Notes

Select this component when a narrowband SAW filter is required at 460 MHz. Consider the 1.5 dB insertion loss and 23.4 MHz bandwidth for system link budget calculations. Ensure the operating environment stays within the specified temperature range for the selected package type.

Part Context

The SF2271C belongs to the RFMi SAW filter family, which offers various center frequencies and bandwidths for different RF applications. These components are typically used to isolate specific frequency bands in wireless transceivers and receivers, providing essential interference rejection.

Replacement Considerations

Check for direct substitutes with identical 460 MHz center frequency and 23.4 MHz bandwidth. Verify pinout compatibility and package dimensions if replacing with other manufacturers' SAW filters. Ensure equivalent insertion loss and impedance characteristics.
