SF2025B

Overview

The SF2025B is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed for 50 Ohm systems. It operates at a center frequency of 259.861 MHz with a bandwidth ranging from 13.8 MHz to 14.5 MHz. The component features an insertion loss of 13.3 dB and supports a rated voltage of 30 V. It is housed in a 10-SMD, no-lead package measuring 7.00 mm x 5.00 mm x 2.00 mm.

Feature Summary

• Utilizes Surface Acoustic Wave technology for signal filtering
• Designed for integration into 50 Ohm system architectures
• Constructed in a compact surface-mount package for automated assembly

Applications

• Satellite Digital Audio Radio Service (SDARS)
• Intermediate Frequency (IF) filtering stages

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to procurement. Confirm that the 10-SMD no-lead package dimensions align with the target PCB footprint. Ensure the operating environment remains within the specified 30 V rating and temperature limits defined in the official documentation.

Selection Notes

Select this component when a SAW filter is required for the 259.861 MHz band with specific bandwidth constraints. Consider the 13.3 dB insertion loss impact on system gain. Verify compatibility with SDARS or IF applications requiring this precise frequency response and physical form factor.

Part Context

This part belongs to the RFMi SAW filter portfolio, now under Akoustis Technologies. These components are engineered for high-frequency signal conditioning in communication devices. The SF2025B specifically targets niche broadcasting standards requiring stable performance in a small outline package.
