Procurement Notes
Verify the specific suffix code against official Radiall documentation to confirm exact electrical tolerances and termination style. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure the 28VDC coil voltage requirement matches your system's power supply capabilities before procurement.
Selection Notes
Select this component when a single-pole triple-throw switching function is required for high-frequency applications up to 18 GHz. The Ramses series offers robust mechanical endurance with a 2 million cycle rating. Ensure the PCB layout supports solder pin mounting and that the thermal environment remains within the specified -40°C to +85°C operational range.
Part Context
This part belongs to the Ramses family of coaxial switches, designed for demanding RF environments. The series provides reliable signal path switching with low insertion loss and high isolation. The R574413320 specifically utilizes an SMA interface, making it suitable for standard microwave interconnect requirements where compact size and high performance are critical.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with existing designs if considering alternative manufacturers, ensuring matching frequency limits, impedance, and mechanical footprint.
