Procurement Notes

Verify current availability status as the product may be subject to last-time-buy restrictions or limited supply conditions. Confirm technical specifications against official datasheets prior to integration. Ensure compliance with regional import regulations and RoHS requirements. Validate control voltage levels match system design parameters.

Selection Notes

Select this component when an eight-channel single-pole switch is required within the 18 GHz bandwidth. Consider the terminated design for improved impedance matching and reduced reflection. Verify that the 12 Vdc power requirement aligns with available system supplies. Assess thermal management needs for the specified operating temperature range.

Part Context

This part belongs to the Ramses family of RF switches, which are engineered for high-reliability applications. The SMA interface provides standardized connectivity for coaxial systems. As a terminated switch, it integrates internal loads to maintain signal integrity across all ports. The module packaging facilitates surface-mount integration into complex RF assemblies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative SP8T switches from the same manufacturer only if they meet identical electrical and mechanical specifications. Cross-reference control logic and form factor before considering any substitution.
