R573113620

Overview

The R573113620 is an SP6T coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It operates within a frequency range of 0Hz to 12.4GHz with a characteristic impedance of 50 Ohms. The device features normally open contacts and provides a minimum isolation of 60dB and a maximum insertion loss of 0.5dB. It utilizes a reflective topology and is designed for panel mounting. The unit includes built-in TTL driver compatibility, suppression diodes, and status indicators. Electrical control is managed via solder pins terminals with a 28Vdc coil voltage requirement.

Feature Summary

• SP6T configuration with normally open contact topology
• Integrated TTL driver compatibility and self-cut-off functionality
• Built-in suppression diodes and status indicators
• Reflective switching design for high-frequency signal routing

Applications

• RF signal distribution in communication systems
• Test and measurement equipment signal routing
• Aerospace and defense electronic warfare systems
• Satellite ground station antenna switching

Procurement Notes

Verify the specific datasheet version and mechanical dimensions prior to integration. Confirm that the 28Vdc coil voltage aligns with the system power supply architecture. Ensure the panel mount footprint matches the enclosure design. Validate that the N-type connector interface is compatible with existing cabling infrastructure. Check for any regional compliance requirements regarding the EAR99 classification.

Selection Notes

Select this component when a six-port RF switching solution is required up to 12.4GHz. The SP6T topology supports complex signal path management compared to simpler SPDT or SP3T alternatives. The integrated TTL driver simplifies control logic interfacing. Consider the 28Vdc requirement against available power rails. The reflective topology may impact source match depending on the application environment.

Part Context

This part belongs to the Ramses Concept R57 family of coaxial switches. The series offers various configurations including SP3T, SP4T, and SP6T options. Models are available with different connector types such as N, TNC, BNC, and SMA. The R573113620 specifically denotes the SP6T variant with N-type connectors and 28Vdc actuation.

Replacement Considerations

Direct substitutes include other Ramses models with equivalent SP6T topology and N-type interfaces. Verify coil voltage compatibility, as 12Vdc variants exist within the same family. Ensure the replacement maintains the 12.4GHz frequency range and 50 Ohm impedance characteristics.
