RF Directional Couplers Procurement Notes

Verify the specific suffix 'ELTR' against official KYOCERA AVX documentation to confirm tape and reel specifications and quantity per reel. Ensure compatibility with RoHS regulations if required, as some variants may not comply. Confirm that the 0603 footprint matches the PCB design constraints. Cross-reference the part number with authorized distributors to validate current availability and lead times prior to ordering.

RF Directional Couplers Selection Notes

Select this component when a 15dB coupling factor is required for the 869-894MHz band. Consider the 3W power rating and 0.35dB insertion loss for low-loss signal paths. The 0603 package size is critical for high-density layouts. Compare isolation (-33dB) and return loss (23dB) against system requirements to ensure adequate signal integrity and minimal reflection in the RF chain.

RF Directional Couplers Part Context
