SF2037B

Overview

The SF2037B is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, an Akoustis brand. It operates at a center frequency of 76.5 MHz with a bandwidth of 3.8 MHz and insertion loss of 10 dB. The device supports the SDARS RF application and features impedance values of 175 Ohms and 1 kOhm. It has a voltage rating of 30 V and is housed in a 10-SMD, no-lead package.

Feature Summary

• Utilizes Surface Acoustic Wave technology for signal filtering
• Designed specifically for SDARS RF applications
• Provides defined impedance matching characteristics

Applications

• SDARS RF signal processing
• Radio frequency filtering systems

Procurement Notes

Verify the specific manufacturer designation, as sources list both RFMi and Akoustis. Confirm the exact bandwidth specification, as documentation varies between 3.8 MHz and 4.1 MHz. Ensure the package type matches the required 10-SMD configuration. Cross-reference part numbers to distinguish between standard and variant designs like the SF2037B-2.

Selection Notes

Select this component for applications requiring a 76.5 MHz SAW filter with 10 dB insertion loss. Consider the 10-SMD package size for board layout constraints. Verify impedance requirements against the 175 Ohm and 1 kOhm specifications provided in technical data sheets.

Part Context

RFMi, now part of Akoustis, specializes in RF components using SAW, crystal, and ceramic technologies. The SF2037B belongs to their line of surface acoustic wave filters designed for digital and wireless communication systems, offering precise frequency control for specialized radio applications.

Replacement Considerations

The SF2037B-2 is listed as a related variant with a different bandwidth of 12.5 MHz. Verify compatibility before substitution due to significant spectral differences.
