R573113615

Overview

The R573113615 is an RF coaxial switch manufactured by Radiall USA, Inc. It features a Single Pole Six Throw (SP6T) configuration with a characteristic impedance of 50 Ohms. The device operates up to a maximum frequency of 12.4 GHz and utilizes a normally open contact arrangement. Control is managed via a D-sub connector interface powered by 28 Vdc. Key electrical specifications include a maximum insertion loss of 0.5 dB and a minimum isolation of 60 dB. The unit supports panel mounting and includes built-in status indicators for operational monitoring.

Feature Summary

• SP6T switching topology for multi-channel signal routing
• High-frequency operation capability up to 12.4 GHz
• Integrated visual status indicators for contact state verification
• D-sub connector interface for TTL-compatible control signals

Applications

• Test and measurement instrumentation systems
• Telecommunications base station infrastructure
• Aerospace and defense electronic warfare suites
• Automated radio frequency testing environments

Procurement Notes

Verify the specific datasheet revision to confirm mechanical dimensions and pinout assignments prior to integration. Ensure that the 28 Vdc control voltage aligns with the system power supply capabilities. Confirm that the panel mount form factor fits within the designated enclosure constraints. Validate that the 50 Ohm impedance matches the surrounding RF transmission line requirements to prevent signal reflection issues.

Selection Notes

Select this component when a high-isolation SP6T switch is required for frequencies approaching 12.4 GHz. The D-sub control interface simplifies wiring compared to discrete driver circuits. Consider the thermal dissipation characteristics if multiple switches are mounted in close proximity. The positive common configuration dictates the signal path behavior during the unactuated state.

Part Context

This part belongs to the Ramses Concept series of coaxial switches from Radiall. The series offers various pole configurations and connector types optimized for demanding RF applications. The R573113615 specifically addresses needs for high-channel-count switching with reliable DC control interfaces. It complements other models in the family that may offer different termination options or actuator types.

Replacement Considerations

Direct substitutes require matching the SP6T topology, 50 Ohm impedance, and 12.4 GHz frequency limit. Verify that alternative components support the same 28 Vdc D-sub control scheme. Mechanical compatibility must be confirmed for panel mounting dimensions. Electrical parameters such as insertion loss and isolation should meet or exceed the original specifications.
