R574312425

Overview

The R574312425 is a terminated SP3T RF switch from the RAMSES series by Radiall USA, Inc. It operates within a frequency range of DC to 3GHz and features SMA connectors. The device has a 50-ohm impedance and requires a 12Vdc TTL supply voltage. It includes normally open indicators and utilizes diodes with D-sub terminals for control.

Feature Summary

• SP3T configuration with terminated ports
• Integrated normally open status indicators
• SMA connector interface
• D-sub terminal control architecture

Applications

• RF signal routing in communication systems
• Test and measurement equipment
• Telecommunications infrastructure

Procurement Notes

Verify the specific model suffix against official Radiall documentation to confirm pinout and control logic compatibility. Ensure the 12Vdc TTL requirement matches the system controller output levels. Confirm SMA connector gender and mating requirements for integration into existing test setups or production lines.

Selection Notes

Select this component when a single-pole triple-throw switching function is required up to 3GHz. The integrated termination simplifies circuit design by eliminating external load components. Consider the D-sub control interface for complex switching sequences requiring multiple control lines.

Part Context

This part belongs to the RAMSES family of coaxial switches designed for high-performance RF applications. The series offers various configurations including SP4T and higher-order switches with different frequency ratings and connector types, providing modular solutions for diverse RF testing needs.

Replacement Considerations

Consult Radiall datasheets for direct substitutes within the RAMSES series. Verify that alternative models match the 3GHz frequency limit, SP3T topology, and 12Vdc control voltage specifications before substitution.
