R574193425

Overview

The R574193425 is a general-purpose SP4T RF coaxial switch manufactured by Radiall USA, Inc. It operates within a frequency range of 0 Hz to 12.4 GHz and maintains a 50 Ohm impedance. The component features normally open contacts and includes integrated TTL indicator diodes for status monitoring. It utilizes a D-sub connector interface and requires a 28 Vdc supply voltage for operation.

Feature Summary

• SP4T switching configuration with normally open contact state
• Integrated TTL indicator diodes for visual status feedback
• D-sub connector interface for control signal routing
• Operates on a 28 Vdc power supply

Applications

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

Procurement Notes

Verify the specific datasheet version and electrical characteristics directly with Radiall USA, Inc. or authorized distributors before procurement. Confirm that the 28 Vdc TTL control interface matches your system design requirements. Ensure compliance with relevant export control classifications such as EAR99 if applicable to your jurisdiction.

Selection Notes

Select this component when a single-pole four-throw switching topology is required up to 12.4 GHz. The inclusion of built-in indicators simplifies diagnostic procedures compared to switches without status feedback. Verify that the D-sub connector form factor fits within the available panel or chassis space constraints of the host assembly.

Part Context

This part belongs to the Ramses series of coaxial switches from Radiall. The series is designed for high-performance RF applications requiring reliable signal path management. The R574193425 variant specifically integrates electronic control features via the D-sub interface, distinguishing it from manual or purely electromechanical alternatives in the broader product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative SP4T switches from Radiall or other manufacturers only after verifying compatibility with the 28 Vdc TTL control logic and D-sub connector pinout specifications.
