R573493205

Overview

The R573493205 is an SP12T coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It utilizes SMA connectors and supports frequencies up to 12.4 GHz. The device features latching technology with self-cut-off functionality and auto-reset capabilities. It operates on a 28Vdc supply and includes integrated indicators and diodes. The unit connects via a D-sub connector interface.

Feature Summary

• SP12T switching configuration for multi-channel signal routing
• Latching mechanism with self-cut-off and auto-reset functions
• Integrated status indicators and protective diodes
• D-sub connector interface for control signals

Applications

• RF test and measurement equipment
• Telecommunications base stations
• Aerospace and defense radar systems
• Automated testing setups requiring signal multiplexing

Procurement Notes

Verify component authenticity through authorized Radiall distributors or certified suppliers. Confirm datasheet revisions and specific lot codes upon order placement. Ensure compatibility with 28Vdc control voltage requirements in system design. Check for RoHS compliance documentation if required by project specifications. Validate connector pinouts against official schematics before integration.

Selection Notes

Select this model when high-port-count switching is required within the SMA frequency range. The latching feature reduces power consumption during static states compared to non-latching alternatives. Consider the D-sub interface for control wiring complexity. Evaluate space constraints as Ramses switches are typically larger than standard relay modules. Ensure thermal management aligns with the specified operating temperature range.

Part Context

This component belongs to the Ramses family of coaxial switches, designed for high-reliability RF applications. The series offers various port configurations (SPnT) and connector types. The R573493205 specifically addresses needs for 12-channel switching with advanced control features like auto-reset and visual status indication, distinguishing it from basic manual or simple electronic switches.

Replacement Considerations

Direct substitutes include other Ramses series models with compatible port counts and connector types, such as R573493005 (SP10T). Verify electrical parameters and mechanical dimensions before substitution. Cross-reference control voltage and interface requirements to ensure system compatibility. Consult Radiall application notes for equivalent performance alternatives.
