R574412620

Overview

The R574412620 is a terminated coaxial switch from the RAMSES series manufactured by Radiall USA, Inc. It features an SP6T circuit configuration with SMA connectors and operates within a frequency range of DC to 18GHz. The device utilizes normally open logic controlled by 12VDC TTL signals via diodes pins terminals. This component is currently classified as obsolete.

Feature Summary

• Terminated SP6T coaxial switch design
• RAMSES series construction for high-frequency performance
• SMA connector interface termination
• 12VDC TTL control logic compatibility

Applications

• General purpose RF signal routing
• Test and measurement equipment
• Telecommunications infrastructure

Procurement Notes

Verify availability through authorized distributors as this part is marked obsolete. Confirm exact pinout and termination specifications against official datasheets before integration. Check for end-of-life status implications on long-term supply continuity.

Selection Notes

Select this component only if SP6T topology and 18GHz bandwidth are required. Ensure system voltage matches the 12VDC TTL requirement. Consider alternative active parts if new designs require ongoing manufacturing support.

Part Context

Part of the RAMSES family of high-performance coaxial switches. Designed for applications requiring reliable switching at microwave frequencies with standardized SMA interfaces.

Replacement Considerations

R574G13345 is a similar terminated RAMSES switch but offers SP3T configuration instead of SP6T.
