R573F02210

Overview

The R573F02210 is an SP12T coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It utilizes SMA connectors and supports frequencies up to 18 GHz. The device operates with a normally open configuration and requires 12 VDC for actuation. Key electrical parameters include a positive common terminal arrangement. The unit features pin terminals for circuit integration and is designed for reliable RF signal routing in high-frequency applications.

Feature Summary

• SP12T switching topology for complex signal routing
• SMA connector interface for standard RF integration
• Normally open operational state for fail-safe design
• 12 VDC control voltage for electronic switching

Applications

• RF test and measurement equipment
• Telecommunications base stations
• Aerospace and defense radar systems
• Satellite communication ground stations

Procurement Notes

Verify the specific Ramses series datasheet for precise insertion loss and isolation values. Confirm that the SMA connector gender matches the system requirements. Ensure the 12 VDC control logic aligns with the host controller output capabilities. Check for any environmental qualification certifications required for the intended deployment location.

Selection Notes

Select this component when a single-pole twelve-throw switching matrix is required. The 18 GHz frequency limit suits most microwave applications. The normally open state provides a defined default condition. Consider the physical size constraints of the PCB layout for the pin terminals. Evaluate thermal management needs if multiple switches are active simultaneously.

Part Context

This part belongs to the Ramses family of coaxial switches, which are known for high performance in RF environments. The R573F02210 specifically addresses the need for multi-path signal selection in compact form factors. It complements other Ramses variants that offer different port counts or connector types like N-type or 3.5mm.

Replacement Considerations

Direct substitutes may include other SP12T switches from Radiall with compatible SMA interfaces. Verify that alternative parts maintain the 18 GHz frequency range and 12 VDC operating voltage. Cross-reference mechanical dimensions to ensure board compatibility.
