SF2038C

Overview

The RFMi SF2038C is a Surface Acoustic Wave (SAW) filter designed for intermediate frequency (IF) receiver applications, specifically Satellite Digital Audio Radio Service (SDARS). Operating at a center frequency of 76.5 MHz, this component provides signal filtering with low insertion loss characteristics. It is housed in a compact 5.0 x 5.0 mm surface-mount case and supports both differential and single-ended input/output configurations. The device complies with Directive 2002/95/EC regarding restricted hazardous substances.

Feature Summary

• Engineered for SDARS IF receiver signal processing
• Supports differential or single-ended interface configurations
• Utilizes a compact 5.0 x 5.0 mm surface-mount package

Applications

• Satellite Digital Audio Radio Service (SDARS) receivers
• Intermediate frequency (IF) filtering stages
• Low insertion loss signal conditioning circuits

Procurement Notes

Verify the specific manufacturer designation, as RFMi products are now manufactured by TST following Murata's transition. Confirm the exact part suffix (e.g., SF2038C-1) to ensure correct packaging and lead time alignment. Cross-reference official datasheets from Akoustis or TST to validate RoHS compliance status and pinout compatibility before integration into production designs.

Selection Notes

Select this component when designing SDARS receivers requiring a 76.5 MHz SAW filter with minimal signal attenuation. Ensure the circuit design accommodates the specified 5.0 x 5.0 mm footprint. Verify that the chosen variant supports the required differential or single-ended topology. Confirm availability through authorized distributors managing the Akoustis/TST product line transition.

Part Context

RFMi is an Akoustis brand specializing in radio frequency components using SAW, crystal, and ceramic technologies. The company focuses on low-power wireless communications and digital signal filtering solutions. This product line includes filters for WiFi, GPS, LTE, and satellite radio applications, emphasizing high performance and reliability in compact form factors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Related variants such as SF2038B or SF2037C exist within the family but require individual electrical parameter verification to determine functional equivalence.
