Procurement Notes
Verify part authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm technical specifications against the official datasheet prior to integration. Ensure compatibility with existing control logic and power supply requirements. Check current product status and availability directly with the supplier as distribution may vary by region.
Selection Notes
Select this component when eight distinct RF paths require switching at frequencies up to 18 GHz. The SP8T configuration suits complex signal routing needs. Verify that the SMA connector type matches system cabling. Ensure the control interface supports the required TTL diode logic and 12Vdc operation for proper functionality within the target application environment.
Part Context
This model belongs to the Ramses series of coaxial switches manufactured by Radiall. The series is designed for high-performance RF applications requiring precise signal switching. The R573402825 variant specifically offers eight output ports controlled via a digital interface, fitting into the broader portfolio of modular RF switching solutions.
Replacement Considerations
Consult Radiall documentation for verified substitute part numbers within the same Ramses series or compatible families. Cross-reference pinouts, control logic, and electrical specifications to ensure functional equivalence before substitution.
