Overview
The R574403320 is a terminated SP3T coaxial switch from the Ramses series, manufactured by Radiall. It features SMA connectors and operates at frequencies up to 18 GHz. The device utilizes a normally open configuration with a 28 VDC coil voltage and TTL diodes for control. It employs solder pin terminals for mounting and has a non-illuminated status. The component is designed for high-frequency signal routing in demanding environments.
Feature Summary
- Terminated single-pole triple-throw (SP3T) switching architecture
- SMA connector interface for standard RF integration
- Normally open contact configuration for default state safety
- Integrated TTL diode control circuitry for drive compatibility
Applications
- High-frequency signal routing in telecommunications infrastructure
- Test and measurement equipment requiring precise path selection
- Radar systems utilizing microwave frequency bands
- Electronic warfare applications needing rapid signal switching
Procurement Notes
Verify current availability as the component is listed as obsolete or end-of-life. Confirm that the specific Ramses series termination matches system requirements. Ensure the 28VDC TTL drive logic aligns with existing control interfaces. Check for any environmental compliance updates prior to final procurement decisions.
Selection Notes
Select this model when an 18 GHz bandwidth is required for SP3T switching. Consider the Ramses series form factor for panel mount constraints. Verify that the SMA interface polarity suits the connected cable assemblies. Evaluate the 28VDC power requirement against available supply rails in the design.
Part Context
This part belongs to the Ramses family of coaxial switches, known for robust performance in microwave applications. It represents a specialized solution for signal distribution where high isolation and low insertion loss are critical. The series supports various configurations tailored for defense and aerospace sectors.
Replacement Considerations
Public confirmed substitute part numbers are not available due to the component's obsolete status. Designers should evaluate newer Ramses series variants or equivalent SP3T switches from other manufacturers if availability is critical.
