Procurement Notes
Verify current lifecycle status as this component may be discontinued or subject to limited supply. Confirm technical specifications against official Radiall datasheets prior to integration. Ensure compatibility with existing 28 Vdc control circuits and D-sub connector interfaces. Validate frequency requirements do not exceed the 18 GHz operational limit. Check for authorized distributor availability due to potential stock constraints.
Selection Notes
Select this model when an SP4T configuration with normally open logic is required for frequencies up to 18 GHz. Ensure system design accommodates the specific 28 Vdc control voltage and D-sub connector form factor. Consider the terminated Ramses SMA interface for impedance matching needs. Verify that the component's physical dimensions and mounting requirements align with the target application enclosure.
Part Context
This part belongs to the Ramses series of coaxial switches from Radiall, designed for robust RF switching applications. The series typically offers various pole configurations and frequency ranges. The R574403435 specifically addresses needs for four-way switching at higher microwave frequencies using standard SMA connectors and industrial control voltages.
