Procurement Notes

Verify component status as the R574412325 is listed as discontinued or obsolescent in official distributor records. Confirm availability through authorized channels or secondary markets. Ensure compatibility with existing 12Vdc TTL control logic and SMA termination requirements before procurement.

Selection Notes

Select this component for applications requiring SP3T switching at frequencies up to 18 GHz. Verify that the normally open default state aligns with system safety requirements. Ensure the D-sub connector form factor fits the enclosure constraints. Confirm TTL voltage levels match the control circuitry.

Part Context

This part belongs to the Ramses series of RF switches from Radiall. It is designed for high-performance microwave applications. The series typically offers robust construction for demanding environments. This specific model integrates diode switching technology for fast response times.

Replacement Considerations

As the part is discontinued, identify equivalent SP3T SMA switches from current Radiall lines or other manufacturers. Verify matching frequency range, control voltage, and connector type. Cross-reference pinouts and mechanical dimensions for direct replacement.
