RSF-773.000-30000-1109-TR

Overview

The RSF-773.000-30000-1109-TR is a surface acoustic wave (SAW) filter manufactured by Raltron Electronics, designed for RF applications in wireless communication systems. It operates at a center frequency of 773 MHz with a bandwidth of 30 MHz. The component features an insertion loss of approximately 2.0 to 2.2 dB and is housed in a compact 5-SMD, no lead package measuring 1.10 mm x 0.90 mm with a maximum height of 0.50 mm.

Feature Summary

• Engineered as a surface acoustic wave filter for precise RF signal processing
• Optimized for operation within the LTE frequency band
• Utilizes a compact 5-SMD no-lead package for space-constrained designs

Applications

• LTE wireless communication modules
• Smartphone RF front-end circuits
• Tablet device signal filtering

Procurement Notes

Verify the specific datasheet version from Raltron Electronics to confirm exact electrical tolerances and pin configurations before integration. Ensure compatibility with the target PCB footprint dimensions of 1.10mm x 0.90mm. Cross-reference with authorized distributors to validate authenticity and supply chain integrity for production runs.

Selection Notes

Select this component when a narrow 30 MHz bandwidth is required at 773 MHz for LTE applications. Consider the low profile and small SMD footprint if board real estate is limited. Compare insertion loss specifications against system link budget requirements to ensure adequate signal integrity without excessive amplification needs.
