RF Directional Couplers Procurement Notes

Verify the specific waveguide interface dimensions and flange type required for your application against the official datasheet specifications. Confirm that the operating frequency range of 29 GHz to 31 GHz aligns with your system requirements. Ensure proper handling procedures are followed due to the precision nature of waveguide components. Check for any specific mounting hardware requirements listed in the product documentation before integration.

RF Directional Couplers Selection Notes

Select this component when a fixed 20 dB coupling factor is needed within the 29-31 GHz band. Consider the physical size and weight constraints associated with WR-28 waveguide structures. Evaluate the insertion loss specification relative to system link budget requirements. Compare available coupling values in the manufacturer's crossguide series if different attenuation levels are necessary for the specific application design.
