Overview
The R574402820 is an SP8T terminated coaxial switch from the Ramses series, manufactured by Radiall USA, Inc. It utilizes SMA connectors and supports a maximum frequency of 18 GHz with a 50 Ohm impedance. The device operates on a normally open configuration requiring 12Vdc control voltage. It features pin terminals for circuit board termination and includes integrated indicators. The component is designed for high-reliability RF signal routing applications.
Feature Summary
- SP8T switching topology with terminated ports
- SMA connector interface for 18 GHz operation
- Normally open state with 12Vdc control
- Integrated status indicators
Applications
- RF signal distribution systems
- Test and measurement equipment
- Telecommunications infrastructure
- Aerospace and defense radar systems
Procurement Notes
Verify RoHS compliance status and lead times directly with authorized distributors. Confirm that the specific variant matches the 12Vdc control requirement and SMA interface specifications. Ensure proper handling procedures are followed due to the sensitive nature of RF components. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.
Selection Notes
Select this component when an eight-channel RF switching solution is required at frequencies up to 18 GHz. The normally open configuration suits applications where default isolation is preferred. Verify compatibility with existing 12Vdc control logic and SMA mating connectors. Consider the physical footprint and terminal type for PCB integration during design phase.
Part Context
This part belongs to the Ramses series of coaxial switches, known for high performance in demanding environments. The SP8T configuration allows routing one input to one of eight outputs. Termination on unused ports ensures stable impedance matching. The Ramses line targets critical applications requiring reliable RF switching capabilities.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Evaluate cross-reference options only if official substitution data is released by the manufacturer. Do not assume functional equivalence with other SP8T switches without verifying electrical parameters and mechanical fit.
