Overview
The R573402800 is an SP8T coaxial RF switch from the Ramses series, manufactured by Radiall USA, Inc. It utilizes SMA connectors and operates up to 18 GHz. The device features a normally open configuration with pin terminals for control. It requires a 12Vdc supply voltage. The component is designed for high-frequency signal routing in demanding environments.
Feature Summary
- SP8T switching topology for multi-channel signal routing
- Ramses series construction for reliable RF performance
- Normally open state configuration for default signal path management
Applications
- Test and measurement equipment requiring multi-port signal selection
- Telecommunications infrastructure systems
- Aerospace and defense electronic warfare suites
Procurement Notes
Verify current availability status directly with the manufacturer or authorized distributors, as lead times may vary. Confirm that the 12Vdc control requirement aligns with system power specifications. Ensure SMA connector compatibility with existing PCB layouts. Check for any recent discontinuation notices or lifecycle changes before finalizing procurement plans.
Selection Notes
Select this component when an eight-channel single-pole switching solution is required at frequencies up to 18 GHz. The normally open configuration suits applications where signal isolation is critical in the idle state. Verify that the 12Vdc control voltage matches available system rails. Consider the Ramses series durability for long-term operational reliability in fixed installations.
Part Context
This part belongs to the Ramses family of coaxial switches, which are engineered for high-reliability applications. The series typically offers robust mechanical and electrical performance suitable for harsh environments. As an SP8T device, it provides extensive routing capabilities within a compact form factor compared to discrete switching solutions.
