- Aerospace and defense radar systems
Procurement Notes
Verify the specific datasheet version for the Ramses series to confirm exact pinout configurations and mechanical dimensions. Ensure that the driving circuitry provides the required 24V to 30V DC coil voltage with appropriate current limits. Confirm compatibility with SMA interface standards for your system integration requirements.
Selection Notes
Select this component when an SP4T switching solution is required for frequencies up to 18 GHz. The Ramses series offers low insertion loss and high isolation suitable for sensitive RF applications. Consider the SMA connector type and D-sub control interface when designing the host board layout and cable assemblies.
Part Context
This part belongs to the Ramses family of microwave switches designed for robust performance in demanding environments. The series typically includes various port configurations and connector options. The R573403445 specifically addresses needs for multi-path signal distribution in high-frequency electronic systems requiring reliable switching characteristics.
Replacement Considerations
Consult official Radiall documentation for direct cross-reference part numbers. Verify that any substitute matches the SP4T topology, 18 GHz frequency limit, and 50-ohm impedance specifications.
