R574313305

Overview

The R574313305 is a terminated SP3T coaxial switch from the Ramses series, manufactured by Radiall. It features SMA connectors and operates up to 3 GHz. The device utilizes a normally open configuration with 28Vdc control voltage and includes indicators. Connection is facilitated via a D-sub connector. This component is classified as obsolete.

Feature Summary

• Terminated single-pole triple-throw (SP3T) switching architecture
• Normally open operational state with integrated status indicators
• 28Vdc electromagnetic actuation mechanism

Applications

• RF signal routing in communication systems
• Test and measurement equipment signal paths
• Aerospace and defense electronic assemblies

Procurement Notes

Verify obsolescence status directly with Radiall or authorized distributors before procurement planning. Confirm availability of last-time buys or equivalent replacements. Ensure compatibility with existing 28Vdc control interfaces and D-sub mounting requirements for integration into current designs.

Selection Notes

Select this component only if SMA interface and 3 GHz bandwidth meet system specifications. Verify that the normally open latching behavior aligns with power-fail safety requirements. Confirm physical space constraints for the D-sub connector housing and bracket options.

Part Context

This part belongs to the Ramses family of high-performance coaxial switches designed for demanding RF applications. The series offers various pole configurations and connector types. The R574313305 specifically addresses needs for terminated SP3T switching at microwave frequencies with robust DC control capabilities.

Replacement Considerations

As an obsolete part, verify cross-reference availability through Radiall engineering support. Check for updated Ramses series variants with compatible electrical parameters and mechanical footprints.
