Overview
The R574403000 is a terminated Ramses coaxial switch manufactured by Radiall USA, Inc. It features an SP10T contact configuration with SMA connectors and operates up to 18 GHz. The device utilizes a 28 VDC coil voltage for normally open operation and employs a positive common D-sub connector for termination. Key electrical parameters include a 50 Ohm impedance, 1.5:1 VSWR, 0.5 dB insertion loss, and 60 dB isolation. The switch supports 2,000,000 cycles and functions within a temperature range of -40°C to +85°C.
Feature Summary
- SP10T switching topology with terminated Ramses architecture
- SMA interface connectors for RF signal routing
- Positive common configuration with D-sub connector termination
- Normally open actuation mechanism

Procurement Notes
Verify component authenticity through authorized Radiall channels due to potential supply chain variations. Confirm specific datasheet revisions and environmental compliance documentation prior to integration. Ensure mechanical compatibility with existing D-sub mounting interfaces and validate thermal management requirements for the specified operating temperature range.
Selection Notes
Select this model when high-port count switching (SP10T) is required in a compact form factor. The terminated Ramses design simplifies PCB layout by integrating matching networks. Verify that the 28 VDC control voltage aligns with system power supplies and that SMA connectivity meets frequency requirements up to 18 GHz.
Part Context
This component belongs to the Ramses series of coaxial switches from Radiall, designed for reliable RF switching in demanding environments. The series offers various pole configurations and termination options to accommodate different system architectures while maintaining consistent performance characteristics across the product line.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific SP10T configuration. Evaluate alternative Ramses series models with compatible port counts and connector types if exact replacement is unavailable.
