RF Directional Couplers Procurement Notes

Verify the exact suffix against official datasheets, as variations like CLTR or FLTR may indicate different tolerance levels or packaging configurations. Confirm RoHS compliance status directly with the manufacturer, as some variants in this series may not meet current environmental standards. Ensure the ordering quantity matches the manufacturer's standard reel size to avoid partial reel handling issues during procurement.

RF Directional Couplers Selection Notes

Select this component when a fixed coupling value near 9.5dB is required at 1.747 GHz. Compare isolation and insertion loss specifications against system requirements to ensure signal integrity. Consider the 0603 package constraints for PCB layout density. Validate that the maximum power rating aligns with the expected operational power levels in the target circuit design.

RF Directional Couplers Part Context
