RF Directional Couplers Procurement Notes

Verify the specific datasheet version for the SMW42EC002-20 to confirm mechanical dimensions and electrical tolerances. Ensure compatibility with WR-42 waveguide standards and UG-595/U flange specifications before integration. Cross-reference the coupling factor tolerance of ±0.8 dB against system requirements. Confirm material composition details if environmental resistance is critical for the intended deployment scenario.

RF Directional Couplers Selection Notes

Select this component when a fixed 20 dB coupling ratio is required within the 18–26.5 GHz spectrum. The WR-42 form factor dictates physical integration constraints. Consider the E-plane port orientation for layout planning. This model is suitable for applications needing stable directional coupling without active components. Evaluate insertion loss and directivity specifications from the official documentation for precision needs.
