RF Switches Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm current availability status, as this part may be classified as obsolete or end-of-life. Ensure that the required supply voltage range of 24 V to 30 V aligns with your system design before procurement. Cross-reference the SP6T configuration and 18 GHz frequency limit against your application requirements to ensure compatibility.

RF Switches Selection Notes

Select this component when an SP6T configuration is required for frequencies up to 18 GHz. Consider the 24–30 V supply requirement and the specific insertion loss and isolation metrics. Evaluate alternative parts if the obsolete status poses a risk to long-term production. Verify that the 50 Ohm impedance matches your system architecture.

RF Switches Part Context

This component belongs to the RAMSES series of RF switches manufactured by Radiall USA, Inc. The series is known for high-frequency performance. The R574493685 specifically implements an SP6T topology. It is distinct from other Radiall products like the R141208000 connector or R222M46012 adapter due to its integrated circuit nature rather than passive interconnect function.

RF Switches Replacement Considerations

Public sources indicate this part has an obsolete status. No confirmed substitute part numbers are provided in the available documentation. Engineers should seek equivalent SP6T RF switches from other manufacturers that meet the 18 GHz, 50 Ohm, and 24–30 V supply specifications.
