Overview
The R574403335 is a SP3T coaxial switch from the Terminated Ramses series by Radiall. It features SMA connectors and operates up to 18 GHz. The device uses normally open contacts and requires 28 VDC coil voltage. Electrical specifications include a maximum insertion loss of 0.5 dB, a VSWR of 1.5:1, and isolation of 60 dB. The unit has a 50 Ohm impedance and utilizes solder pin terminals for PCB mounting.
Feature Summary
- SP3T switching configuration with normally open contact logic
- Terminated Ramses design for stable RF performance
- SMA connector interface supporting frequencies up to 18 GHz
- 28 VDC electromagnetic coil actuation mechanism
Applications
- Aerospace and defense signal routing systems
- Test and measurement equipment RF paths
- Telecommunications infrastructure switching modules
Procurement Notes
Verify component authenticity through authorized Radiall distributors or official channels. Confirm current lifecycle status as availability may be restricted. Ensure compatibility with 28 VDC control circuits and SMA mating interfaces before integration. Request updated datasheets to validate electrical parameters against specific application requirements.
Selection Notes
Select this model for applications requiring high-frequency switching up to 18 GHz with low insertion loss. The SP3T topology allows routing one input to three outputs. Verify mechanical fit for solder pin termination and board edge constraints. Consider thermal management capabilities within the specified operating temperature range during system design.
Part Context
This component belongs to the Terminated Ramses family of coaxial switches designed for demanding environments. The series emphasizes reliability and consistent RF characteristics across wide bandwidths. Radiall manufactures these interconnect solutions primarily for aerospace, defense, and industrial sectors requiring robust electronic switching.
Replacement Considerations
Consult official Radiall documentation for direct cross-reference part numbers. Evaluate alternative models within the same Ramses series for similar frequency and port configurations. Verify that substitute components match the 28 VDC coil requirement and SMA interface specifications.
