R573413345

Overview

The Radiall R573413345 is a coaxial switch from the RAMSES series, configured as an SP3T (Single Pole Three Throw) unit. It operates with SMA connectors and supports frequencies up to 18 GHz. The device utilizes a normally open configuration with positive common terminals and includes integrated indicators for status visibility. Power requirements are specified at 28 Vdc, and it features suppression diodes for protection. Connectivity is established via a D-sub connector interface.

Feature Summary

• SP3T switching topology with SMA interfaces supporting up to 18 GHz
• Normally open operation with positive common terminal configuration
• Integrated visual indicators for operational status monitoring
• Built-in suppression diodes with D-sub connector actuation

Applications

• RF signal routing in high-frequency test and measurement systems
• Telecommunications infrastructure requiring reliable microwave switching
• Aerospace and defense electronic warfare subsystems

Procurement Notes

Verify current manufacturing status directly with Radiall USA, Inc., as lifecycle information may be incomplete. Confirm availability through authorized distributors or direct factory channels, as standard stock levels are not publicly guaranteed. Ensure compatibility with existing 28 Vdc control logic and D-sub connector wiring before procurement.

Selection Notes

Select this component when an SP3T coaxial switch is required for applications operating up to 18 GHz. The choice is appropriate for systems needing positive common configurations with integrated status indicators. Verify that the D-sub connector interface aligns with the host system's control architecture and that the 28 Vdc power supply matches available plant utilities.

Part Context

This part belongs to the RAMSES concept family of coaxial switches by Radiall. The series offers various configurations including different throw counts, connector types, and driver options. This specific model represents a high-frequency solution designed for robust performance in demanding RF environments, distinguishing itself through its specific combination of SMA connectivity and 18 GHz bandwidth.

Replacement Considerations

Consult official Radiall documentation for confirmed substitute part numbers within the same RAMSES series. Cross-reference specifications such as frequency range, connector type, and control voltage to ensure functional equivalence. Do not assume interchangeability with other manufacturers' products without verifying detailed electrical and mechanical parameters.
