Overview
The R574393300 is a Radiall coaxial switch featuring an SP3T configuration with SMA terminated Ramses connectors. It operates up to 3 GHz and utilizes a latching mechanism powered by 28 VDC coil voltage. The device employs solder pin terminals for PCB mounting and maintains a 50 Ohm impedance. Key electrical specifications include a maximum VSWR of 1.5:1, insertion loss of 0.5 dB, and isolation of 60 dB. It supports a mechanical life of 2,000,000 cycles within a temperature range of -40°C to +85°C.
Feature Summary
- SP3T switching topology with latching functionality
- SMA terminated Ramses connector interface
- 28 VDC coil voltage operation
- Solder pin terminal mounting style
Applications
- RF signal routing in communication systems

Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm current availability status as supply may be restricted or limited. Ensure compatibility with existing PCB layouts regarding pin dimensions and spacing. Review environmental compliance documentation for specific project requirements. Validate technical specifications against latest manufacturer datasheets before final integration.
Selection Notes
Select this component when a latching SP3T coaxial switch is required for frequencies up to 3 GHz. The 28 VDC drive voltage suits standard control logic interfaces. Solder pin termination is appropriate for rigid PCB assembly processes. Consider the 50 Ohm impedance match for standard RF applications requiring low insertion loss and high isolation performance.
Part Context
This part belongs to the Radiall Ramses series of coaxial switches, designed for robust RF performance. The series offers various pole configurations and connector types. The R574393300 specifically addresses needs for reliable signal switching in demanding environments using a latching mechanism to maintain state without continuous power.
Replacement Considerations
Consult official Radiall substitution guides for verified alternatives. Cross-reference specifications such as frequency range, contact configuration, and mounting style. Verify that any substitute matches the 28 VDC coil requirement and SMA connector type. Ensure physical footprint compatibility for direct replacement.
