RF Directional Couplers Procurement Notes

This component is listed as End-of-Life (EOL) or discontinued by the manufacturer. Availability is restricted, and Mouser currently indicates that the product is not sold in certain regions. Verification of current stock status and alternative sourcing channels is essential before procurement planning. Due to the discontinued status, lead times may be indefinite or unavailable through standard distribution networks. Confirm compatibility with existing SMA connector interfaces when evaluating replacement options.

RF Directional Couplers Selection Notes

Select this component for applications requiring precise signal coupling within the 2 GHz to 4 GHz band. Ensure the system environment remains within the specified -10 °C to +65 °C operating temperature range. Verify that the interface requirements match the SMA connector type provided. Consider the discontinued status when designing long-term production cycles, as future supply continuity cannot be guaranteed. Evaluate mechanical space constraints against the miniature form factor enabled by the stripline triplate design.
