R573002800

Overview

The R573002800 is a single-pole eight-throw (SP8T) coaxial RF switch manufactured by Radiall USA, Inc. It operates within the Ramses series and utilizes N-type connectors. The component supports a maximum frequency of 3 GHz and maintains a characteristic impedance of 50 Ohms. Designed for normally open operation, it requires a 12 Vdc actuation voltage with pin terminals. The unit is supplied in bulk packaging.

Feature Summary

• Single-pole eight-throw switching topology
• Normally open configuration
• N-type connector interface

Applications

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

Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and mating cycle ratings. Ensure the 12 Vdc control voltage aligns with system power supplies. Confirm that the N-type connector gender matches the application cabling requirements before finalizing procurement.

Selection Notes

Select this component when an SP8T switching solution is required at frequencies up to 3 GHz. The normally open state suits applications requiring default isolation. Verify that the N-type interface is compatible with existing RF cabling and that the 12 Vdc control logic fits the driving circuit design constraints.

Part Context

This part belongs to the Ramses series of coaxial switches from Radiall. The series includes various throw configurations and connector types. This specific model provides high-isolation switching capabilities suitable for demanding RF environments where reliable signal path management is critical.

Replacement Considerations

Cross-reference with other Ramses series models for different throw counts or connector interfaces. Verify electrical compatibility if substituting with generic SP8T switches. Ensure the replacement maintains the 50 Ohm impedance and 3 GHz frequency rating.
