Procurement Notes

Verify component authenticity through authorized Radiall channels or certified distributors. Confirm datasheet revisions and RoHS compliance status prior to integration. Ensure storage conditions align with manufacturer specifications to maintain connector integrity and switching reliability over the operational lifespan.

Selection Notes

Select this model when a single-pole ten-throw switching solution is required for signals up to 18 GHz. The latching design ensures state retention without continuous power. Verify that the 28 Vdc control voltage and TTL input requirements match the system's available logic levels and power supply architecture for proper actuation.

Part Context

This component belongs to the Ramses family of coaxial switches, engineered for high-reliability applications. The series offers various throw configurations and connector types, maintaining consistent electrical performance standards across the product line while adapting to specific interface and path count requirements.

Replacement Considerations

Consult official Radiall documentation for direct cross-reference part numbers. Verify mechanical footprint, connector type, and control voltage compatibility before substituting. Ensure any alternative maintains the 18 GHz frequency limit and SP10T topology.

FAQ

What is the control voltage requirement for the latching mechanism?

The switch requires a 28 Vdc supply to operate the latching coils.

Does the switch retain its state after power loss?

Yes, the latching design retains the selected path state until a new command is issued.
