Overview
The R574403245 is a terminated coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It features an SP12T configuration with SMA connectors and operates up to 12.4 GHz. The device utilizes normally open contacts with positive common logic and requires a 28Vdc control voltage. Diodes are integrated for protection, and it connects via a D-sub connector. This component is designed for high-frequency RF signal routing applications.
Feature Summary
- SP12T switched configuration for multi-path signal routing
- Terminated design ensuring stable impedance matching
- Integrated diode protection circuitry
- D-sub connector interface for control signals
Applications
- High-frequency RF test and measurement equipment
- Telecommunications base station signal distribution
- Aerospace and defense radar systems
- Satellite communication ground stations
Procurement Notes
Verify current lifecycle status as sources indicate obsolete or limited availability. Confirm exact frequency specifications against official datasheets due to conflicting reports of 12.4 GHz versus 18 GHz ratings. Ensure compatibility with existing 28Vdc control interfaces and D-sub connector requirements before integration into final designs.
Selection Notes
Select this model when a high-port-count SP12T switch is required within the Ramses series. Consider the terminated architecture for applications demanding consistent load conditions. Verify that the SMA connector type aligns with system cabling needs. Evaluate the 28Vdc positive common control scheme against available driver electronics to ensure proper interfacing without additional level-shifting components.
Part Context
This component belongs to the Ramses family of coaxial switches, known for robust performance in demanding environments. The R574403245 specifically addresses scenarios requiring extensive signal path switching capabilities. Its design emphasizes reliability and precise RF characteristics, serving as a critical node in complex radio frequency infrastructure where signal integrity is paramount.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the specific SP12T configuration and Ramses series architecture, direct replacements may require redesigning the control interface and mechanical footprint. Consult manufacturer resources for potential obsolescence management options.
