Procurement Notes
This component is currently listed as obsolete or discontinued by the manufacturer. Availability is restricted, and distributors may indicate limited stock or non-sale status in specific regions. Verify end-of-life status and lead times carefully before design-in. Sourcing should focus on remaining inventory from authorized channels or approved secondary markets.
Selection Notes
Select this part for high-frequency switching requirements up to 18GHz with low insertion loss. Ensure compatibility with 12Vdc TTL control levels and D-sub physical interfaces. Consider the SP6T topology for complex signal routing needs. Verify thermal performance within the specified -40°C to 85°C operating range for your environment.
Part Context
Part of the Ramses family of RF switches, designed for robust performance in demanding environments. The terminated version includes internal termination resistors for improved VSWR characteristics. This specific model integrates SMA connectors and digital control for precise signal management in high-speed RF systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require evaluating similar Ramses series models or consulting manufacturer engineering support for cross-reference data.
