R574413020

Overview

The R574413020 is an RF coaxial switch manufactured by Radiall USA, Inc. It belongs to the Ramses Concept series and features a Single Pole Ten Throw (SP10T) configuration. The device operates with SMA connectors and supports frequencies up to 18 GHz. It utilizes a terminated design and includes a built-in TTL driver for control. The unit is designed for panel mounting and functions as a normally open switch.

Feature Summary

• Integrated TTL driver for simplified control logic
• Terminated architecture for stable signal performance
• High-frequency operation capability up to 18 GHz

Applications

• RF signal routing in communication systems
• Test and measurement equipment switching
• Aerospace and defense radar applications

Procurement Notes

Verify the specific datasheet revision and pinout configuration before integration. Confirm that the 18 GHz frequency rating aligns with system requirements. Ensure panel mounting provisions match the enclosure design. Validate compatibility with the intended control voltage levels for the TTL interface.

Selection Notes

Select this component when a high-port-count SP10T switch is required within the Ramses family. Consider the terminated design if impedance matching is critical at the output ports. Evaluate the 18 GHz bandwidth against higher-frequency alternatives if needed. Verify the SMA connector type matches existing cabling infrastructure.

Part Context

This part is part of the Radiall Ramses Concept R57 series, which offers various configurations of coaxial switches. The series provides options for different port counts and termination styles. The R574413020 specifically addresses needs for multi-path switching in high-frequency environments.

Replacement Considerations

Check for updated versions within the R5744 series. Verify mechanical dimensions and pin assignments against potential substitutes. Ensure electrical specifications such as isolation and insertion loss meet or exceed original requirements.
