Overview
The Radiall R573403335 is a general-purpose SP3T coaxial RF switch from the Ramses series. It operates at frequencies up to 18 GHz with a 50 Ohm impedance. The device utilizes normally open contacts and is driven by a 28 VDC coil voltage. It features a D-sub connector interface for control signals. Key electrical specifications include a VSWR of 1.5:1, insertion loss of 0.5 dB, and isolation of 60 dB.
Feature Summary
- SP3T switching configuration for signal routing
- High-frequency operation up to 18 GHz
- Normally open contact design
- D-sub connector interface for control
Applications
- RF signal routing in communication systems
- Test and measurement equipment
- Aerospace and defense radar systems
Procurement Notes
Verify the specific datasheet version and manufacturing lot details before procurement. Confirm that the D-sub connector orientation and pinout match your system requirements. Ensure the 28 VDC drive voltage is compatible with your control circuitry. Check for any environmental certifications or compliance documents required for your specific application domain.
Selection Notes
Select this component when an SP3T switching solution is required for frequencies up to 18 GHz. The normally open configuration suits applications where the default state must be isolated. Consider the D-sub interface if space constraints favor this connector type over other control interfaces. Verify that the 50 Ohm impedance matches the rest of the RF chain to minimize reflections.
Part Context
This part belongs to the Ramses series of coaxial switches manufactured by Radiall USA, Inc. The Ramses line is designed for high-performance RF applications requiring reliable switching in demanding environments. This specific model represents a standard offering within the series, balancing frequency performance with robust mechanical construction.
Replacement Considerations
Consult official Radiall documentation for verified substitute part numbers. Cross-referencing should focus on matching SP3T topology, 18 GHz frequency limit, and 28 VDC drive requirements. Ensure physical footprint and connector compatibility are maintained during substitution.
