Overview
The R574402815 is an SP8T coaxial switch from the Terminated Ramses series by Radiall USA, Inc. It operates within a frequency range of DC to 18 GHz. The device features a normally open configuration with positive common logic and requires 12Vdc for actuation. It utilizes a D-sub connector for control interface termination. The component is designed for high-reliability RF signal routing applications.
Feature Summary
- SP8T switching topology with positive common logic
- Terminated Ramses SMA interface design
- 12Vdc powered normally open operation
- D-sub connector for control termination
Applications
- RF signal routing in test and measurement equipment
- Telecommunications base station switching matrices
- Aerospace and defense radar systems
- Automated test system configurations
Procurement Notes
Verify part authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm specific revision levels and packaging details against official datasheets prior to order placement. Ensure compatibility with existing control voltage requirements and mechanical mounting constraints in the target assembly.
Selection Notes
Select this model when an eight-port switching solution with positive common logic is required. The 18 GHz bandwidth supports wideband RF applications. Consider the D-sub control interface for integration with standard industrial control hardware. Evaluate thermal management needs based on continuous power handling specifications in the technical data sheet.
Part Context
This component belongs to the Terminated Ramses family of coaxial switches. The series offers multiple port configurations including SP4T, SP6T, SP8T, SP10T, and SP12T variants. All models share similar SMA interface characteristics and controlled actuation methods, providing scalable switching solutions for complex RF architectures.
Replacement Considerations
Cross-reference with other SP8T Ramses models such as R574402815 derivatives if availability is constrained. Verify that substitute parts maintain identical 12Vdc control requirements and D-sub connector pinouts to ensure mechanical and electrical compatibility without circuit redesign.
