R573003405

Overview

The Radiall R573003405 is an SP4T coaxial switch from the Ramses N series, operating up to 3 GHz. It features a normally open configuration with positive common contacts and utilizes N-type connectors. The device is designed for panel mounting and operates on a 28Vdc coil voltage. Key electrical specifications include a minimum isolation of 80 dB and a maximum insertion loss of 0.2 dB. The unit maintains a 50 Ohm impedance and functions within a temperature range of -40°C to 85°C.

Feature Summary

• SP4T switching topology with positive common contact configuration
• Normally open operational state for signal routing control
• High isolation performance ensuring minimal signal leakage between ports

Applications

• RF signal distribution networks requiring multi-port switching
• Test and measurement equipment utilizing N-type interfaces
• Telecommunications infrastructure components

Procurement Notes

Verify the specific connector type and mounting style against project requirements before ordering. Confirm that the 28Vdc coil voltage aligns with available power supplies in the target system. Ensure the panel mounting dimensions fit the designated enclosure space. Check for any updated datasheet revisions that may affect mechanical or electrical tolerances.

Selection Notes

Select this component when an SP4T configuration is required for N-type connections. The 3 GHz frequency limit suits many standard RF applications. Consider the 28Vdc drive requirement for circuit design compatibility. The normally open state defines the default signal path behavior upon power loss.

Part Context

This part belongs to the Ramses N series of coaxial switches manufactured by Radiall. The series is characterized by robust construction suitable for demanding RF environments. The N-type interface provides reliable connectivity for frequencies up to 11 GHz, though this specific model is rated for 3 GHz operation.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other Ramses N series variants for similar SP4T configurations. Verify mechanical footprint and pinout compatibility if considering alternative manufacturers.
