R574382225

Overview

The R574382225 is a single-pole, twelve-throw (SP12T) coaxial RF switch manufactured by Radiall USA, Inc. It belongs to the Ramses series and utilizes SMA connectors for interfacing. The component operates at a maximum frequency of 3 GHz with a characteristic impedance of 50 Ohms. It features terminated ports and is designed for surface-mount or panel integration contexts depending on the specific housing configuration. The device supports 12V DC control signals and includes integrated diode protection for the D-sub connector interface used for command input.

Feature Summary

• High-density switching capability with twelve distinct output paths managed by a single input port.
• Integrated termination on all unused or selected ports to maintain signal integrity and reduce reflections.
• Built-in diode protection circuitry connected to the D-sub control interface to safeguard against electrical transients.
• Standard SMA connector interface ensuring compatibility with common RF test and measurement infrastructure.

Applications

• Automated RF test and measurement systems requiring multi-channel signal routing
• Telecommunications base station testing environments
• Radar system simulation and analysis setups

Procurement Notes

Verify the specific datasheet revision and mechanical drawing before procurement, as Ramses series switches may have variant housing options. Confirm that the 12V DC control voltage aligns with your system's power supply capabilities. Ensure the D-sub connector pinout matches your controller's output specifications to guarantee correct switching logic operation during integration.

Selection Notes

Select this component when a high-port-count RF switch is required within the 3 GHz frequency range. The SP12T topology is suitable for applications needing extensive signal path selection from a single source. Consider the physical footprint and thermal dissipation requirements associated with solid-state switching elements in dense PCB layouts compared to electromechanical alternatives.

Part Context

This part is part of Radiall's Ramses family of solid-state RF switches, which are known for high reliability and fast switching speeds. The R574382225 specifically addresses the need for complex signal routing in compact form factors. It complements other Ramses variants like the SP4T and SP8T models by offering higher channel density for advanced system architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with existing system designs if considering alternative manufacturers, as control logic and connector types may differ significantly between solid-state RF switch families.
