R573412820

Overview

The R573412820 is an SP8T coaxial switch from the Ramses series by Radiall USA, Inc. It utilizes SMA connectors and supports frequencies up to 18 GHz with a 50 Ohm impedance. The device operates on a normally open configuration, controlled by a 12Vdc TTL signal. Key electrical features include diode pins for control and pin terminals for connection. The unit is designed for robust RF signal routing in high-frequency applications.

Feature Summary

• SP8T switching topology for multi-path signal distribution
• SMA interface compatible with standard RF infrastructure
• Normally open state ensures default isolation
• Integrated indicator functionality for status monitoring

Applications

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

Procurement Notes

Verify current availability directly with Radiall or authorized distributors as stock levels fluctuate. Confirm lead times for bulk orders. Ensure compatibility with 12Vdc TTL control signals. Check for RoHS compliance documentation if required for specific regulatory environments. Validate connector type and mounting style against system requirements.

Selection Notes

Select this component when an eight-way RF switching solution is required within the 18 GHz bandwidth. The SMA interface suits existing infrastructure using standard connectors. The 12Vdc TTL control level aligns with common digital logic outputs. Consider the normally open state for safety-critical designs requiring default isolation. Evaluate thermal management needs based on power handling specifications.

Part Context

This part belongs to the Ramses family of coaxial switches, designed for high-performance RF applications. The series offers various port configurations (SP4T, SP6T, SP8T) and control options. The R573412820 specifically provides eight output paths, making it suitable for complex signal routing tasks in dense RF environments where minimal insertion loss and high isolation are critical.

Replacement Considerations

Cross-reference with other Ramses series models like R573403540 (SP5T) or R573412600 (SP6T) if fewer ports suffice. Verify that substitute parts maintain the same SMA interface, 18 GHz frequency limit, and 12Vdc TTL control voltage. Ensure mechanical dimensions and terminal types match the existing PCB layout or chassis mounting constraints.
