RSF-2605.000-140000-1109-TR-NS1

Overview

The RSF-2605.000-140000-1109-TR-NS1 is a Surface Acoustic Wave (SAW) filter manufactured by Raltron Electronics, designed for high-frequency RF signal conditioning in mobile communication devices. It operates at a center frequency of 2.605 GHz with a bandwidth of 140 MHz and features an insertion loss of 2.0 dB. The component utilizes a compact 5-SMD, No Lead package, suitable for space-constrained applications such as smartphones and LTE modules.

Feature Summary

• Surface Acoustic Wave technology for precise RF filtering
• Optimized for cellular frequency bands including LTE
• Compact surface-mount design for automated assembly

Applications

• Smartphone RF front-end modules
• LTE wireless communication devices
• Mobile broadband terminals

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations exist between tape-and-reel and cut-tape formats. Confirm that the 5-SMD no-lead package matches your PCB footprint requirements. Cross-reference the datasheet revision date to ensure compliance with current manufacturing standards and material specifications before finalizing procurement orders.

Selection Notes

Select this component when a 2.605 GHz center frequency with 140 MHz bandwidth is required for LTE applications. Compare insertion loss specifications against system sensitivity requirements to ensure adequate signal integrity. Ensure the 5-SMD package dimensions align with available board space constraints and thermal management strategies for dense mobile device layouts.

Part Context

This part belongs to the RSF series of SAW filters from Raltron Electronics, specifically engineered for cellular applications. It complements other variants in the family that offer different bandwidths or frequencies, providing designers with modular solutions for various global LTE bands and mobile communication protocols requiring reliable RF signal processing.

Replacement Considerations

Direct substitutes include RSF-2605.000-100000-1109-TR-NS1, which shares the same frequency but offers a 100 MHz bandwidth instead of 140 MHz. Verify that the reduced bandwidth meets the specific channel requirements of the target application before substitution.
