R570533040

Overview

The R570533040 is a single-pole double-throw (SPDT) coaxial switch from the Ramses series manufactured by Radiall. It features TNC connectors and operates up to 3 GHz. The device utilizes a latching mechanism powered by 28Vdc with positive common polarity. Electrical connections are established via diodes, pins, and terminals. This component is designed for high-frequency signal routing applications requiring reliable switching performance within its specified frequency range.

Feature Summary

• Single-pole double-throw configuration for signal path selection
• Latching operation maintained by 28Vdc power supply
• TNC connector interface for coaxial integration
• Positive common polarity with diode-based control

Applications

• RF signal routing in communication systems
• Test and measurement equipment setups
• Aerospace and defense radar subsystems
• Wireless infrastructure signal distribution

Procurement Notes

Verify availability directly with Radiall or authorized distributors as stock status may vary. Confirm technical specifications against the official datasheet before procurement. Ensure compatibility with 28Vdc latching drivers and TNC mating interfaces. Check for any specific environmental certifications required for your application environment.

Selection Notes

Select this model when SPDT switching at frequencies up to 3 GHz is required. The TNC interface suits standard coaxial cabling needs. The latching feature reduces power consumption during steady states. Ensure the system provides stable 28Vdc for proper actuation and maintains positive common logic levels for control signals.

Part Context

This component belongs to the Ramses family of coaxial switches, known for robust performance in RF environments. The R570 series typically denotes N-type or similar connector variants, while the 533 suffix indicates TNC connectors in this specific part number. It serves as a critical passive switching element in complex RF front-end architectures.

Replacement Considerations

Direct substitutes include other Ramses series SPDT switches with compatible connector types and voltage requirements. Verify that replacement parts maintain the same 3 GHz frequency limit and 28Vdc latching specifications. Ensure mechanical footprint and terminal pinout compatibility if board-level integration is planned.
