RF Directional Couplers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required termination and packaging specifications. Confirm that the selected variant meets all environmental compliance standards relevant to your target market before finalizing procurement orders.

RF Directional Couplers Selection Notes

Select this component when a 20 dB coupling factor is required at the 2.1-2.2 GHz band. Ensure the design accommodates the 0.35 dB insertion loss and 25 dB return loss specifications. The 0402 package size dictates strict PCB land pattern adherence to maintain electrical integrity and mechanical reliability during assembly.

RF Directional Couplers Part Context

This part belongs to the CP0402P series of high-directivity couplers from KYOCERA AVX. These components are engineered for general-purpose RF applications requiring precise signal splitting or tapping. The series leverages advanced thin-film deposition techniques to achieve consistent performance across varying temperature conditions.

RF Directional Couplers Replacement Considerations

Consult official substitution lists for equivalent thin-film couplers with matching 20 dB coupling and 0402 dimensions. Verify impedance matching and frequency response overlap before considering alternative manufacturers or series replacements.
