R573403415

Overview

The R573403415 is a general-purpose SP4T RF switch from the Ramses series, manufactured by Radiall USA, Inc. It operates at frequencies up to 18 GHz with a 50-ohm impedance. The device features a normally open configuration and utilizes a positive common D-sub connector interface. It requires a 28 Vdc coil voltage for operation. Key electrical specifications include a maximum insertion loss of 0.5 dB, a minimum isolation of 60 dB, and a VSWR of 1.5:1. The unit is packaged in bulk.

Feature Summary

• SP4T switching topology with normally open logic
• High-frequency performance up to 18 GHz
• Positive common control via D-sub connector
• Low insertion loss and high isolation characteristics

Applications

• RF signal routing in communication systems
• Test and measurement equipment configurations
• Aerospace and defense radar subsystems
• Satellite ground station signal distribution

Procurement Notes

Verify the specific datasheet version and mechanical dimensions prior to integration. Confirm that the 28 Vdc control voltage aligns with system power supplies. Ensure the D-sub connector mating requirements are compatible with existing cabling infrastructure. Check for any environmental certifications required for the intended deployment location.

Selection Notes

Select this component when a four-way signal path switching solution is required within the 18 GHz bandwidth. The SP4T configuration supports complex network topologies requiring multiple output selection. Consider the 28 Vdc drive requirement against available control logic levels. Evaluate the bulk packaging format against assembly line handling capabilities.

Part Context

This part belongs to the Ramses family of coaxial switches designed for robust RF applications. The series offers various port configurations including SP3T and SP5T variants. These components are engineered for reliability in demanding environments, providing consistent electrical performance across wide frequency ranges while maintaining compact form factors suitable for modular systems.

Replacement Considerations

Compatible substitutes include other Ramses series models such as R573403315 (SP3T) or R573403005 (SP10T). Verify port count compatibility and control voltage requirements before substitution. Ensure the replacement maintains the 18 GHz frequency limit and 50-ohm impedance specification.
