R574332805

Overview

The R574332805 is a terminated Ramses series coaxial switch manufactured by Radiall USA, Inc. It features an SMA interface and operates as a Single-Pole Eight-Throw (SP8T) configuration with a maximum frequency of 3 GHz. The device utilizes a normally open topology and is controlled via a 12 Vdc input, compatible with D-sub connectors. Key material specifications include PTFE dielectric and gold-plated contacts, ensuring performance within a temperature range of -65°C to 165°C.

Feature Summary

• Terminated Ramses architecture for integrated RF switching
• SP8T topology supporting eight distinct signal paths
• Normally open state with 12 Vdc electromagnetic control

Applications

• RF signal routing in communication systems
• Test and measurement equipment requiring multi-port switching
• Aerospace and defense radar subsystems

Procurement Notes

Verify the obsolete status and limited supply availability through official Radiall channels before procurement. Confirm that the D-sub connector interface aligns with existing system requirements. Ensure compliance with RoHS3 standards and check for any specific handling instructions related to the terminated module design during installation.

Selection Notes

Select this component when an SP8T switching solution with SMA connectivity is required. The 3 GHz frequency limit and 12 Vdc control voltage are critical constraints. Consider the terminated Ramses form factor for space-constrained applications where integrated switching is preferred over discrete components.

Part Context

This part belongs to the Ramses family of coaxial switches, designed for high-reliability RF applications. The SPnT series offers various throw configurations, with the R574332805 specifically providing eight output ports. It represents a specialized solution for complex signal distribution networks in professional electronic systems.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the obsolete status of this specific model. Alternative solutions may require redesigning the switching topology or selecting newer Ramses series variants with updated interfaces.
