Procurement Notes
Verify part authenticity through authorized Radiall distributors. Confirm specific control interface requirements (BCD vs TTL) and termination status against project specifications. Check current lifecycle status as availability may vary. Ensure environmental ratings meet operational temperature constraints.
Selection Notes
Select this component for applications requiring eight-way RF switching at frequencies up to 18 GHz. Consider the module form factor and SMA interface compatibility. Evaluate power consumption against available supply rails within the 10.2V to 13V range. Assess thermal management needs for the specified operating temperature range.
Part Context
This component belongs to the Ramses family of coaxial switches, designed for robust performance in demanding environments. The terminated design simplifies integration by eliminating the need for external load terminations on unused ports. It serves as a critical interconnect element in complex RF signal distribution networks.
Replacement Considerations
Consult Radiall documentation for direct equivalents within the Ramses series. Verify pinout and control logic compatibility before substituting. Ensure replacement parts meet identical frequency and impedance specifications.
