RF Directional Couplers Procurement Notes

Verify the specific datasheet version for the SMW28HC001-20 to confirm mechanical interface compatibility and environmental ratings. Ensure that the operating frequency aligns strictly with the 26.5 GHz to 40 GHz range. Check for any required mating waveguide components or flanges necessary for system integration before finalizing procurement orders.

RF Directional Couplers Selection Notes

Select this component when a 20 dB coupling ratio is required for the E-band spectrum. Consider the 40 dB directivity specification for applications demanding high measurement accuracy. Evaluate the 0.7 dB insertion loss against system budget constraints. Confirm that the physical dimensions fit within the available space in the waveguide assembly.

RF Directional Couplers Part Context

This part belongs to Fairview Microwave's waveguide coupler series, specifically tailored for millimeter-wave frequencies. It serves as a passive component for directing a portion of the main signal path to a secondary port. The design supports standard WR-28 waveguide interfaces commonly used in radar and communication systems.
