Procurement Notes

Verify the specific datasheet version and mechanical drawings prior to integration. Confirm that the D-sub connector mating requirements align with system harness designs. Ensure environmental ratings meet operational temperature ranges. Cross-reference part numbers to avoid confusion with similar Ramses variants.

Selection Notes

Select this model when high-port count switching is required in compact form factors. The 26.5 GHz rating suits broadband applications. Verify compatibility with 28 Vdc control logic. Consider the D-sub termination method for panel mounting constraints compared to direct cable options.

Part Context

This component belongs to the Ramses family of coaxial switches, designed for reliable RF signal management. The series offers various pole counts and frequency ranges. The R573F13815 specifically addresses needs for eight-way switching at microwave frequencies using standard SMA interfaces.

Replacement Considerations

Check Radiall documentation for direct equivalents within the R573 series. Verify pinout compatibility for D-sub connections. Ensure frequency and voltage specifications match existing system requirements before substitution.
