R574303800

Overview

The R574303800 is an SP8T terminated coaxial switch from the Ramses series manufactured by Radiall. It features SMA connectors and operates up to 3 GHz. The device utilizes a normally open configuration with 28Vdc control voltage and pin terminals. This component is designed for high-performance RF signal routing in demanding applications.

Feature Summary

• SP8T topology providing eight distinct output paths
• Terminated design ensuring stable impedance matching
• Normally open switching state for default isolation
• SMA interface compatible with standard RF infrastructure

Applications

• RF test and measurement equipment
• Telecommunications base stations
• Aerospace and defense radar systems
• Electronic warfare signal processing

Procurement Notes

Verify current availability status as this component may be subject to limited supply or end-of-life restrictions. Confirm that the specific package type and terminal configuration match your board layout requirements. Ensure compatibility with the required 28Vdc control logic before finalizing procurement orders.

Selection Notes

Select this model when an eight-port distribution path is required within the 3 GHz frequency range. The normally open characteristic suits applications requiring default isolation states. Verify that the SMA connector style aligns with existing cable assemblies and system interconnect standards.

Part Context

This part belongs to the Ramses family of terminated coaxial switches. It shares architectural similarities with other models like R574323300 but differs in port count and switching state. The series is engineered for robust performance in critical RF environments.

Replacement Considerations

Direct substitutes include R574303615 for SP6T configurations or R574302805 for SP8T normally open variants. Cross-reference datasheets to ensure identical voltage requirements and connector types before substitution.
