RF Directional Couplers Procurement Notes

Verify the specific ordering suffix to ensure compliance with RoHS standards and lead-free requirements. Confirm that the selected variant matches the required surface-mount footprint and thermal specifications for your target application environment. Cross-reference the manufacturer's latest documentation to validate current production status and availability before finalizing procurement plans.

RF Directional Couplers Selection Notes

Select this component when a 9 dB coupling ratio is required within the 2.3 GHz to 4.3 GHz band. Ensure the system can accommodate the specified 1.7 dB maximum insertion loss. Verify that the 2 Watt power handling capability aligns with the maximum expected signal levels in the circuit path to prevent component damage during operation.

RF Directional Couplers Part Context
