Procurement Notes
Verify component authenticity through authorized Radiall distributors or certified suppliers. Confirm the specific datasheet revision matches application requirements. Check for obsolescence status as availability may be limited. Ensure environmental compliance documentation is available if required for the target market. Validate connector pinout compatibility with existing system designs before procurement.
Selection Notes
Select this model for applications requiring high-frequency switching up to 18 GHz with precise signal routing. Consider the 28 VDC latching requirement for power supply design. Evaluate the D-sub connector form factor against panel space constraints. Compare performance metrics such as VSWR and isolation against alternative RF switches to ensure signal integrity meets system specifications.
Part Context
This component belongs to the Ramses series of coaxial switches from Radiall. It is designed for robust RF performance in demanding environments. The SP8T topology allows for complex signal path management. The terminated design ensures stable impedance matching across all ports. This series is commonly used in professional-grade electronic testing setups.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation.
