RSF-1457.000-20000-1411-TR

Overview

The RSF-1457.000-20000-1411-TR is a Surface Acoustic Wave (SAW) bandpass filter manufactured by Raltron Electronics. It operates at a center frequency of 1457 MHz with a bandwidth of 20 MHz, covering a range from 1447 to 1467 MHz. The component features an insertion loss of 1.4 dB and is housed in a compact 5-SMD, No Lead package with a maximum height of 0.60 mm. Designed for surface mount technology, this active RF filter supports LTE applications.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF signal filtering
• Optimized for LTE frequency bands with defined bandwidth characteristics
• Compact leadless SMD package design suitable for space-constrained layouts

Applications

• LTE communication systems
• Smartphone RF front-end modules
• Wireless device signal processing

Procurement Notes

Verify the complete part number including the -TR suffix to ensure correct tape-and-reel packaging configuration. Confirm that the 5-SMD no-lead package dimensions align with your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the operating temperature range meets your specific environmental conditions before finalizing procurement.

Selection Notes

Select this component when a narrow 20 MHz bandwidth is required around the 1457 MHz center frequency. The low insertion loss of 1.4 dB makes it suitable for sensitive RF paths. Consider the 5-SMD package size relative to available board space. Verify compatibility with your assembly process for leadless surface mount components.

Part Context

This SAW filter belongs to Raltron's extensive family of RF filters designed for mobile communications. The RSF series targets high-volume consumer electronics markets, particularly smartphones and wireless devices requiring reliable LTE performance. The specific model addresses the need for compact, high-performance filtering solutions in modern portable electronics.

Replacement Considerations

No public substitute part numbers are confirmed for this specific component. Cross-referencing requires matching the exact 1457 MHz center frequency, 20 MHz bandwidth, 1.4 dB insertion loss, and 5-SMD package dimensions. Consult manufacturer documentation for potential alternatives.
