R573112405

Overview

The R573112405 is a general-purpose RF coaxial switch manufactured by Radiall USA, Inc. It features an SP4T topology with a frequency range of 0Hz to 12.4GHz and a characteristic impedance of 50 Ohms. The device provides a minimum isolation of 60dB. It operates on a 12Vdc supply and utilizes a D-sub connector for control inputs.

Feature Summary

• SP4T reflective circuit topology
• Broadband operation up to 12.4GHz
• High isolation performance
• D-sub connector interface

Applications

• RF signal routing in test and measurement equipment
• Telecommunications base station switching
• Aerospace and defense radar systems
• Electronic warfare applications

Procurement Notes

Verify the specific datasheet version and mechanical dimensions prior to procurement. Confirm that the D-sub connector pinout matches the system design requirements. Ensure the 12Vdc control voltage aligns with the available power supply infrastructure in the target application environment.

Selection Notes

Select this component when high-frequency switching up to 12.4GHz is required with minimal insertion loss. The SP4T configuration allows routing one common port to four distinct output ports. Consider the panel mount form factor and D-sub control interface compatibility during system integration planning.

Part Context

This part belongs to the Ramses N series of coaxial switches from Radiall. The series offers various configurations including SP3T and SP6T options. These switches are designed for robust performance in demanding RF environments, providing reliable signal switching capabilities across wide bandwidths.

Replacement Considerations

Check for direct substitutes within the same Ramses family, such as R573102320 or R573112600, ensuring topology and connector types match. Verify that any alternative maintains the 12.4GHz frequency limit and 50 Ohm impedance specifications.
