RF Directional Couplers Procurement Notes

Verify that the specific suffix 'CSTR' corresponds to the required tape and reel packaging configuration for your manufacturing line. Confirm that the component's non-RoHS status aligns with your project's environmental compliance requirements. Ensure the 3W power handling capacity meets the peak power demands of your specific RF application before finalizing procurement orders.

RF Directional Couplers Selection Notes

Select this component when a fixed coupling factor near 13.5dB is required at 1.975 GHz. Consider the 0805 package size constraints and the need for SMD termination. Evaluate if the specified isolation and return loss metrics satisfy the system's signal integrity requirements compared to alternative coupler models.
