R573102605

Overview

The R573102605 is a high-frequency RF switch manufactured by Radiall USA, Inc., belonging to the Ramses N series. It functions as a Single Pole Six Throw (SP6T) coaxial switch with a nominal impedance of 50 Ohms. The device operates up to a maximum frequency of 12.4 GHz and utilizes a normally open contact configuration. Control is achieved via a 12Vdc coil voltage, managed through a D-sub connector interface. This component is designed for general-purpose RF signal routing applications requiring reliable switching performance at microwave frequencies.

Feature Summary

• SP6T coaxial switching architecture for multi-path signal routing
• Operational capability extending to 12.4 GHz frequency range
• Normally open contact configuration ensuring default isolation
• D-sub connector interface for standardized control integration

Applications

• General-purpose RF signal routing in test equipment
• Microwave communication system signal path selection
• High-frequency measurement setup configurations

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as supply conditions may vary. Confirm that the D-sub connector interface aligns with existing control hardware requirements. Ensure the 12Vdc coil voltage specification matches the available control power supply within the target system design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a six-port output distribution or selection is required within the 12.4 GHz operational bandwidth. The SP6T topology supports complex signal routing topologies compared to simpler single-pole designs. Consider the physical footprint and D-sub connector compatibility during mechanical integration planning to ensure proper interfacing with control circuitry.

Part Context

This part belongs to the Ramses N series of coaxial switches from Radiall. The series offers various throw configurations including SP3T, SP4T, SP5T, and SP6T variants. These switches are engineered for high-frequency applications, providing consistent electrical performance across the microwave spectrum while maintaining robust mechanical reliability for repeated switching cycles.

Replacement Considerations

Compatible alternatives within the same family include R573102500 (SP5T) and R573102405LP (SP4T Low PIM). Verify that the reduced port count of these substitutes meets the specific routing requirements of the application. Ensure control voltage and connector type specifications remain compatible with the existing system infrastructure.
