R574303840

Overview

The R574303840 is a terminated coaxial switch manufactured by Radiall USA, Inc., belonging to the Ramses series. It features an SMA interface and supports frequencies up to 3 GHz. The device is configured as an SP8T (Single Pole, 8 Throw) switch with latching indicators. It operates on a 28Vdc supply and utilizes a D-sub connector for control interfacing. The component is currently in active production status.

Feature Summary

• Terminated Ramses series architecture for reliable signal routing
• SP8T configuration providing eight distinct output paths
• Integrated latching indicators for visual state monitoring
• D-sub connector interface for standardized control input

Applications

• RF signal distribution systems requiring multi-path switching
• Test and measurement equipment needing automated port selection
• Telecommunications infrastructure utilizing SMA interfaces
• Automated testing setups with D-sub control requirements

Procurement Notes

Verify the specific Ramses series termination configuration against system impedance requirements before integration. Confirm that the 28Vdc operating voltage aligns with available control power supplies. Ensure the D-sub connector type matches existing cabling or adapter solutions. Check for any updated datasheet revisions regarding mechanical dimensions or electrical tolerances prior to final design approval.

Selection Notes

Select this component when an SP8T switching topology is required within the 3 GHz frequency range. The terminated design suits applications where load matching is critical. Consider the 28Vdc control requirement and D-sub interface compatibility during system design. Evaluate space constraints relative to the physical footprint of the Ramses series housing.
