RF Directional Couplers Procurement Notes

Verify the exact frequency band specification against the official datasheet, as model suffixes may indicate variations in center frequency or tolerance. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements to avoid partial reel handling issues during procurement.

RF Directional Couplers Selection Notes

Select this component when a low-profile, high-directivity coupler is required for AMPS or similar narrowband RF applications. Consider the 0402 package size constraints and the 3W power rating relative to your system's peak power levels. Compare insertion loss and isolation specifications against other series members if tighter tolerances or different coupling factors are needed for your specific circuit topology.
