Procurement Notes
Verify component availability directly with the manufacturer or authorized distributors, as stock status may vary. Confirm that the specific Ramses series variant matches system requirements for frequency range and connector type. Ensure compatibility with the required 28 VDC control voltage and D-sub interface before finalizing procurement orders.
Selection Notes
Select this model when an SP3T coaxial switch is required for applications operating up to 18 GHz. Verify that the SMA connector style aligns with existing cable assemblies. Confirm that the normally open logic and positive common control scheme fit the system's power management architecture. Check that the D-sub connector interface is compatible with the driving electronics.
Part Context
This component belongs to the Ramses series of high-performance coaxial switches from Radiall. The series is designed for demanding RF environments requiring low insertion loss and high isolation. The R573403315 specifically integrates SMA interfaces and D-sub control connections within this robust hardware platform.
Replacement Considerations
Consult official Radiall documentation for verified substitute part numbers within the Ramses series. Cross-reference specifications such as frequency limits, contact configuration, and connector types to ensure functional equivalence. Do not assume interchangeability without validating technical parameters against the original datasheet.
