R574003300

Overview

The R574003300 is a single-pole triple-throw (SP3T) RF coaxial switch manufactured by Radiall USA, Inc. It belongs to the Ramses N series and operates up to a maximum frequency of 3 GHz. The device features a normally open configuration with terminated connections. It utilizes a D-sub connector for control interface and requires a 28Vdc supply voltage. The unit is packaged in bulk and is currently listed as an active product.

Feature Summary

• Single-pole triple-throw switching topology
• Terminated Ramses N interface design
• Normally open operational state
• Integrated D-sub control connector

Applications

• RF signal routing in communication systems
• Test and measurement equipment setups
• Aerospace electronic subsystems

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as stock levels may vary. Confirm that the 28Vdc TTL control requirement matches your system's power supply capabilities. Ensure the D-sub connector type aligns with your existing cabling infrastructure before finalizing procurement orders.

Selection Notes

Select this component when a reliable SP3T switching solution is required for frequencies up to 3 GHz. The normally open default state suits applications where signal paths remain inactive until triggered. Consider the terminated Ramses N connectors for direct integration into compatible RF chains without additional adapters.

Part Context

This part is part of Radiall's Ramses N series of coaxial switches. The series is designed for high-performance RF applications requiring robust switching capabilities. The R574003300 specifically offers three output ports controlled via a standard D-sub interface, providing flexibility in signal distribution tasks within constrained environments.

Replacement Considerations

Consult official Radiall documentation for verified substitute part numbers. Cross-reference specifications such as frequency range, port count, and control voltage to ensure functional equivalence. Do not assume compatibility based on similar series names alone.
