RF Directional Couplers Procurement Notes

Verify compliance with RoHS directives prior to procurement, as this specific part number may not meet current environmental standards. Confirm that the 0402 package dimensions align with your PCB layout requirements. Ensure the operating temperature range of -40°C to +85°C suits your application environment. Validate the 3W power rating against peak signal levels in your circuit design to prevent component failure.

RF Directional Couplers Selection Notes

Select this component when a compact, unidirectional coupler is required for the 1.8 GHz cellular band. The 15.5 dB coupling factor is suitable for sampling signals without significant attenuation. Consider the 0402 size constraint if board space is limited. Compare specifications against other CP0402 series variants if different coupling values or frequency ranges are needed for alternative system architectures.

RF Directional Couplers Part Context

This component belongs to the CP0402 series of RF thin-film directional couplers from KYOCERA AVX. The series offers low profile designs with flat coupling characteristics across specified bands. These devices are engineered for high reliability in mobile communication applications, providing consistent performance in small form factors suitable for modern electronic assemblies.

RF Directional Couplers Replacement Considerations

Check manufacturer documentation for exact substitute part numbers within the CP0402 family. Verify that any replacement maintains identical coupling coefficients, frequency ranges, and physical dimensions to ensure seamless integration without redesigning the host circuit board.
