SF2037C

Overview

The SF2037C is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed specifically for Satellite Digital Audio Radio Service (SDARS) intermediate frequency receivers. It operates at a center frequency of 76.5 MHz with a bandwidth of 4.1 MHz. The device features an impedance configuration of 175 Ohms and 1 kOhm, supporting both differential and single-ended input/output configurations. Rated for a voltage of 30 V, it is housed in a compact 5.0 x 5.0 mm surface-mount package.

Feature Summary

• Designed for SDARS IF receiver applications
• Supports differential or single-ended input and output
• Surface-mount construction in a 5.0 x 5.0 mm case

Applications

• SDARS IF Receiver systems

Procurement Notes

Verify the manufacturer source, as Akoustis has acquired RFMi components. Confirm the specific package variant matches the 8-SMD requirement. Ensure compliance with RoHS directives if required by your design specifications. Check lead times as they may vary based on current production schedules.

Selection Notes

Select this component when a 76.5 MHz SAW filter is required for SDARS applications. Consider the 175/1000 Ohm impedance match for your circuit design. Evaluate the 8-SMD package size against available board space. Verify compatibility with differential or single-ended signal paths.

Part Context

RFMi, now part of Akoustis, specializes in RF components using SAW, crystal, and ceramic technologies. The SF2037C belongs to their SAW filter lineup, targeting digital and wireless communication systems. This series provides frequency control elements for transmitters and receivers.

Replacement Considerations

Murata Manufacturing Co lists the SF2037C as a compatible part number with identical specifications. Verify pinout and electrical characteristics before substitution.
