Procurement Notes
Verify the specific datasheet version and technical parameters directly with Radiall USA, Inc. or authorized distributors before procurement. Confirm that the 28 Vdc coil voltage and D-sub connector requirements align with system design constraints. Ensure compliance with RoHS directives if applicable to the project specifications.
Selection Notes
Select this component when an SP4T switching solution is required for applications operating up to 18 GHz. The 50 Ohm impedance matches standard RF systems. Consider the 28 Vdc control voltage and D-sub interface compatibility during system integration planning. Evaluate the 0.5 dB insertion loss and 60 dB isolation against link budget requirements.
Part Context
This part belongs to the Ramses series of coaxial switches from Radiall. The series offers various configurations including SP3T and SP5T variants with different frequency ranges and control voltages. The R573403425 specifically targets general purpose applications requiring reliable switching at 18 GHz with SMA interfaces.
Replacement Considerations
The R573403425LP is listed as a related variant in public documentation, potentially indicating a Low PIM (Passive Intermodulation) version. Verify pinout and electrical specifications before substitution.
