Procurement Notes

Verify the specific datasheet version for the R574313425 to confirm electrical tolerances and mechanical dimensions. Ensure compatibility with existing SMA mating interfaces and control voltage requirements before procurement. Cross-reference manufacturer documentation for any recent design changes or obsolescence notices.

Selection Notes

Select this component when a four-port single-pole switching solution is required at frequencies up to 3 GHz. The terminated nature simplifies PCB layout by integrating connector interfaces directly into the module. Evaluate thermal management needs based on the operating environment and power handling capabilities defined in the official specifications.

Part Context

This part belongs to the RAMSES family of terminated coaxial switches, which integrate connectors directly onto the switch module. This design reduces insertion loss and improves reliability compared to discrete switch and connector assemblies. The series supports various port configurations and frequency ranges for diverse RF applications.

Replacement Considerations

R574313340 is a documented parameter-equivalent alternative offering SP3T configuration. Verify port count differences and interface compatibility when substituting.
