R574102405

Overview

The R574102405 is a coaxial RF switch manufactured by Radiall USA, Inc., belonging to the Ramses series. It features an SP4T circuit configuration with terminated ports and operates within a frequency range of 0Hz to 12.4GHz. The component utilizes N-type connectors and is designed for normally open operation. Electrical control is achieved via a 12Vdc supply, and the unit includes a D-sub connector for interface connectivity.

Feature Summary

• SP4T switched topology with permanently terminated output ports
• Operates in normally open state with integrated indicator functionality
• N-type connector interface supporting frequencies up to 12.4GHz
• Controlled by 12Vdc input signal with D-sub connector integration

Applications

• RF signal routing in communication test equipment
• Terminated load switching in microwave measurement systems
• Signal path management in radar subsystems
• Automated testing setups requiring high-frequency termination

Procurement Notes

Verify availability status directly with the manufacturer or authorized distributors, as inventory levels may be restricted. Confirm that the 12Vdc control voltage and D-sub connector specifications align with existing system requirements. Ensure compatibility with N-type interfaces and validate operational parameters against specific application needs before procurement.

Selection Notes

Select this component when a terminated SP4T switching solution is required for frequencies extending to 12.4GHz. Consider the normally open default state and 12Vdc control logic during system design. Verify that the D-sub connector form factor fits the enclosure constraints and that the Ramses series performance characteristics meet the specific impedance and isolation requirements of the target application.

Part Context

This part belongs to the Ramses series of coaxial switches from Radiall, designed for high-performance RF applications. The series typically offers robust construction suitable for demanding environments. The R574102405 variant specifically integrates termination resistors into the switch structure, simplifying system design by eliminating the need for external loads at the unused ports.

Replacement Considerations

Consult official Radiall documentation for verified substitute part numbers within the Ramses family. Cross-reference specifications such as frequency range, connector type, and control voltage to ensure functional equivalence. No alternative part numbers are confirmed in the provided data.
