Procurement Notes
Verify the specific datasheet version and electrical characteristics directly from Radiall USA, Inc. before integration. Confirm that the 28 Vdc operating voltage aligns with your system power supply constraints. Ensure SMA connector compatibility with existing PCB layouts. Validate RoHS compliance status for your region's regulatory requirements. Cross-reference the part number with official manufacturer catalogs to confirm current production status.
Selection Notes
Select this component when a single-pole twelve-throw switching architecture is required for signals up to 18 GHz. The 50 Ohm impedance matches standard RF transmission lines. Consider the physical size and SMA interface requirements against available board space. Evaluate the 28 Vdc control voltage against available logic levels or driver circuits. Compare performance metrics against alternative SP12T solutions if higher frequencies or different packaging are needed.
Part Context
This part belongs to the Ramses series of high-frequency RF switches produced by Radiall USA, Inc. The series focuses on reliable signal routing in demanding environments. The R573F03220 variant specifically integrates SMA connectors for standardized interfacing. It serves as a critical interconnect element in complex RF signal chains requiring precise path selection.
Replacement Considerations
Consult Radiall USA, Inc. documentation for direct cross-references. Verify functional equivalence regarding SP12T topology, 18 GHz frequency limit, and 50 Ohm impedance. Ensure SMA connector type and pin terminal mounting match the original design. Check control voltage specifications to guarantee compatibility with existing drive circuits.
