R574392325

Overview

The R574392325 is a single-pole triple-throw (SP3T) RF switch from Radiall's Terminated Ramses series. It features SMA connectors and operates within a frequency range of 0 Hz to 3 GHz. The device utilizes a 50 Ohm impedance system and is designed for general-purpose applications. This component is currently classified as obsolete by the manufacturer, indicating it is no longer in active production.

Feature Summary

• Single-pole triple-throw switching configuration
• Terminated Ramses series design
• SMA connector interface

Applications

• General purpose RF signal routing
• Test and measurement equipment
• Telecommunications systems

Procurement Notes

This component is officially listed as obsolete by Radiall USA, Inc. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the physical condition and electrical integrity of available units, as new manufacturing is discontinued.

Selection Notes

Engineers requiring this specific SP3T topology with SMA interfaces should consider the Terminated Ramses series characteristics. Due to the obsolete status, alternative sourcing strategies are necessary. Selection should prioritize verified availability over standard supply chain channels, ensuring compatibility with existing 50 Ohm system requirements.

Part Context

The R574392325 belongs to Radiall's Terminated Ramses family of coaxial switches. This series is known for providing reliable RF switching solutions with terminated ports to improve isolation performance. The model represents a specific configuration within this broader product line, tailored for frequencies up to 3 GHz.

Replacement Considerations

As the part is obsolete, direct replacements may not be available from the original manufacturer. Engineers should evaluate other SP3T switches from the same Terminated Ramses series or comparable models from other vendors that match the SMA interface and 3 GHz frequency limit.
