R574312430

Overview

The R574312430 is a terminated coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It features an SP4T configuration with SMA connectors and operates within a frequency range of 0 Hz to 3 GHz. The device utilizes a normally open indicator mechanism and requires a 28 Vdc actuation voltage. It is designed for high-reliability applications requiring precise signal routing in RF systems.

Feature Summary

• Terminated Ramses series design for stable impedance matching
• SP4T switching topology for multi-path signal distribution
• SMA connector interface for standard RF integration
• Normally open indicator status visualization

Applications

• RF signal routing in communication infrastructure
• Test and measurement equipment signal paths
• Aerospace and defense electronic systems
• Industrial automation control circuits

Procurement Notes

Verify the specific datasheet version for the R574312430 to confirm current manufacturing status, as some sources indicate this model may be obsolete. Ensure compatibility with 28 Vdc control signals and SMA mating interfaces before procurement. Cross-reference part numbers with official Radiall documentation to avoid substitution errors.

Selection Notes

Select this component when a terminated SP4T switch is required for frequencies up to 3 GHz. Consider the Ramses series benefits for high reliability and the specific need for normally open indicators. Verify that the SMA interface and 28 Vdc actuation requirements align with the system design constraints.

Part Context

This component belongs to the Ramses family of coaxial switches, known for robust performance in demanding environments. The R574312430 specifically addresses applications needing four-way signal switching with termination to minimize reflections. It represents a specialized solution within Radiall's broader portfolio of RF interconnect and switching products.

Replacement Considerations

Check for direct replacements within the Ramses series or other Radiall SP4T models with compatible SMA interfaces and 3 GHz bandwidth. Verify electrical parameters such as insertion loss and isolation if substituting with non-terminated variants.
