R573403680

Overview

The Radiall R573403680 is an SP6T coaxial switch from the Ramses series, designed for high-frequency applications up to 18 GHz. It features a normally open configuration and operates with a 28Vdc coil voltage. The device utilizes an SMA interface and includes a D-sub connector for control signals. Constructed for reliability, it maintains a 50-ohm impedance and offers high isolation characteristics suitable for complex RF signal routing in demanding environments.

Feature Summary

• SP6T switching topology for multi-path signal distribution
• Normally open state ensures default non-conductive paths
• SMA interface compatibility for standard RF connections
• D-sub connector integration for simplified control wiring

Applications

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

Procurement Notes

Verify current availability status directly with Radiall USA, Inc., as distribution channels may indicate limited or restricted supply regions. Confirm that the 28Vdc operating voltage aligns with existing system power architectures. Ensure mechanical fitment of the D-sub connector matches the host panel design requirements before finalizing procurement orders.

Selection Notes

Select this component when six distinct output paths are required from a single input source at frequencies reaching 18 GHz. The normally open logic is critical for safety or default-state applications where signal interruption is preferred upon power loss. Verify that the D-sub control interface is compatible with the available driver circuitry and voltage levels within the target system design.

Part Context

This part belongs to the Ramses family of coaxial switches, which are engineered for robust performance in harsh environments. The Ramses series typically combines high power handling with low insertion loss. The R573403680 specifically addresses the need for multi-port switching in compact form factors, serving as a key interconnect solution in modern RF infrastructure.

Replacement Considerations

Consult official Radiall documentation for direct cross-reference part numbers within the Ramses series. Verify pinout compatibility for the D-sub connector if substituting with other SP6T models. Ensure replacement units maintain the same 18 GHz frequency limit and 28Vdc coil specification to preserve system integrity.
