R573J22645

Overview

The R573J22645 is a SP6T coaxial switch from the Ramses series, designed for high-frequency applications up to 50 GHz. It features a latching mechanism with positive common configuration and utilizes Diodes technology. The unit operates on 12Vdc power and includes a D-sub connector interface. Constructed as a terminated module, it supports signal routing in demanding RF environments while maintaining precise switching states without continuous power consumption.

Feature Summary

• SP6T single-pole six-throw switching architecture
• Ramses series design optimized for frequencies up to 50 GHz
• Latching operation with positive common terminal configuration
• Integrated Diodes technology for reliable signal control

Applications

• High-frequency test and measurement instrumentation
• Wireless communication base station infrastructure
• Satellite ground station signal routing
• Defense and aerospace radar systems

Procurement Notes

Verify the specific Ramses series datasheet for detailed electrical parameters such as insertion loss and isolation before integration. Confirm that the 12Vdc latching requirement aligns with your system's power supply capabilities. Ensure the D-sub connector mating compatibility with existing harnesses. Validate frequency performance specifications against your operational bandwidth requirements to guarantee signal integrity at 50 GHz.

Selection Notes

Select this component when a SP6T topology is required for signals extending to 50 GHz. The latching feature reduces power consumption compared to non-latching alternatives. The positive common configuration suits applications requiring a shared return path or reference. Consider the D-sub interface if panel mounting or specific cabling standards are mandated by the system design constraints.

Part Context

This part belongs to Radiall's Ramses family of high-performance coaxial switches. The series is engineered for robustness in critical RF applications. The R573J22645 variant specifically addresses the need for multi-port switching with latching stability. It complements other Ramses models offering different port counts or frequency ranges within the same product line.

Replacement Considerations

Consult official Radiall documentation for direct cross-reference part numbers. Verify mechanical footprint and D-sub pinout compatibility with alternative suppliers. Ensure equivalent 50 GHz frequency coverage and latching voltage specifications match the original design intent.
