• Compact surface-mount design suitable for space-constrained PCB layouts
• Optimized for LTE band operations with specified bandwidth characteristics

Applications

• LTE wireless communication modules
• Smartphone RF front-end circuits
• Portable electronic devices requiring 780 MHz filtering

Procurement Notes

Verify the complete part number including the NS1 suffix against official Raltron documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the 5-SMD package variant matches your assembly requirements. Cross-reference the datasheet for exact mechanical tolerances and soldering profiles before integration into production lines.

Selection Notes

Select this component when a narrow bandpass filter centered at 780 MHz is required for LTE applications. The low insertion loss of 1.7 dB supports efficient signal transmission. Ensure the operating environment stays within the -30°C to +85°C range. The small footprint allows for dense circuit board designs compared to larger filter technologies.

Part Context

This SAW filter belongs to Raltron's extensive family of RF filters tailored for mobile communications. The specific model targets the 780 MHz spectrum, commonly utilized in LTE bands. Its miniature form factor aligns with industry trends toward miniaturization in consumer electronics and IoT devices requiring reliable RF performance in limited spaces.

Replacement Considerations

Consult Raltron's official substitution guide for compatible alternatives. Verify that any substitute maintains the 780 MHz center frequency, 44.5 MHz bandwidth, and 5-SMD package compatibility to ensure seamless integration without redesigning the PCB layout.
