RSF-915.000-26000-2015-TR

Overview

The RSF-915.000-26000-2015-TR is a Surface Acoustic Wave (SAW) filter manufactured by Raltron Electronics, designed for RF applications in the 915 MHz ISM band. It features a center frequency of 915.000 MHz with a bandwidth of 26 MHz (902–928 MHz). The device exhibits typical and maximum insertion losses of 2.3 dB and 3.0 dB, respectively, within the passband. Operating at an impedance of 50 Ω, it supports a temperature range from -40°C to +85°C. The component is housed in a compact 4-SMD, No Lead package measuring 2.0 x 0.60 x 1.5 mm.

Feature Summary

• Surface Acoustic Wave technology for efficient RF signal filtering
• Optimized for 915 MHz ISM band operations
• Compact surface-mount design suitable for space-constrained PCBs

Applications

• LoRa communication systems
• ISM band general purpose RF filtering
• Wireless sensor networks operating at 915 MHz

Procurement Notes

Verify the specific suffix (e.g., -NS3) against the required datasheet revision when ordering. Confirm that the 4-SMD no-lead package dimensions match the target footprint. Ensure the operating temperature range meets environmental requirements. Cross-reference the manufacturer part number with official Raltron documentation to confirm current production status and specifications before finalizing procurement.

Selection Notes

Select this component for applications requiring precise filtering in the 902–928 MHz range. Consider the low insertion loss characteristics for signal integrity. Evaluate the small form factor against available board space. Verify compatibility with 50 Ω system impedance. Check thermal performance limits if operating near extreme temperatures.

Part Context

This SAW filter belongs to Raltron's family of RF components targeting industrial, scientific, and medical bands. It serves as a specialized solution for wireless data transmission where narrowband filtering is critical. The device complements other Raltron filters designed for different frequency ranges, providing consistent performance metrics across their product line for global wireless standards.

Replacement Considerations

Consult official Raltron substitution guides for verified equivalents. Generic replacements may not match the specific 26 MHz bandwidth or insertion loss profiles. Ensure any substitute maintains the 4-SMD no-lead package and 50 Ω impedance to avoid re-engineering the host circuit.
