Overview
The RSF-797.000-12000-1411-TR is a Surface Acoustic Wave (SAW) filter manufactured by Raltron Electronics, designed for cellular and LTE RF applications. It operates at a center frequency of 797MHz with a bandwidth of 12MHz. The component features a 3dB insertion loss characteristic and is housed in a compact 5-SMD surface-mount package measuring 1.40mm x 1.10mm.
Feature Summary
- Utilizes Surface Acoustic Wave technology for efficient RF signal filtering
- Optimized for cellular and LTE communication bands
- Compact 5-SMD footprint suitable for space-constrained designs
Applications
- Cellular device front-end modules
- LTE receiver input stages
- RF signal conditioning in mobile handsets
Procurement Notes
Verify the complete part number including the -TR suffix to ensure correct tape-and-reel packaging configuration. Confirm that the 797MHz center frequency aligns with specific regional LTE band requirements. Check datasheet specifications for operating temperature range and soldering profile compatibility before integration into production lines.
Selection Notes
Select this component when a low-profile SAW filter is required for 797MHz LTE signals. The 5-SMD package offers a small form factor compared to larger ceramic or metal can alternatives. Ensure the 12MHz bandwidth meets the system's channel spacing needs and that the 3dB insertion loss is acceptable within the link budget calculations.
Part Context
This part belongs to the Raltron RSF series of SAW filters, which are engineered for high-performance RF applications in mobile communications. The series provides various center frequencies tailored to different global cellular standards, ensuring compatibility with modern wireless infrastructure and terminal equipment requirements.
Replacement Considerations
Consult official substitution lists for equivalent SAW filters with matching 797MHz center frequency and 5-SMD package dimensions. Verify pinout compatibility and electrical parameters such as bandwidth and insertion loss before replacing the original component.
