RF Directional Couplers Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging configuration. Confirm that the required tolerance levels for coupling factor and isolation meet the design specifications before finalizing procurement orders. Ensure compliance with environmental regulations such as RoHS3 where applicable.

RF Directional Couplers Selection Notes

Select this component when a standard coupling factor near 25dB is required within the 698MHz to 2.62GHz band. Consider the low insertion loss and high isolation characteristics for sensitive receiver paths. Evaluate the 0603 package size against available PCB real estate constraints during the schematic capture phase.

RF Directional Couplers Part Context
