R573493420 is listed in the RF Switches range at ChipApex. The manufacturer field lists Radiall USA, Inc.. Its product description is IC RF SWITCH SP4T 18GHZ. Review the specifications below when checking this part for your BOM.
The R573493420 is a single-pole four-throw (SP4T) RF switch manufactured by Radiall USA, Inc. It operates within a frequency range of 0 Hz to 18 GHz and maintains a characteristic impedance of 50 Ohms. This component functions as an integrated circuit designed for routing radio frequency signals from one input to four selectable outputs. The device supports general-purpose applications requiring precise signal path selection in high-frequency environments.
Verify the specific datasheet version with the manufacturer before procurement, as specifications may vary. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure that the required lead time aligns with project schedules, noting standard delivery periods may apply. Cross-reference part numbers carefully to avoid confusion with similar models in the Ramses series.
Select this component when a compact SP4T solution is required for frequencies up to 18 GHz. Consider the 50 Ohm impedance match for compatibility with standard RF systems. Evaluate thermal management requirements if operating near maximum frequency limits. Verify interface compatibility with existing PCB layouts and control logic before integration into the design.
This part belongs to the Ramses series of coaxial switches from Radiall. It represents a specialized RF component designed for high-frequency signal integrity. The series is known for reliability in demanding electronic environments. Understanding its position within the broader product line aids in identifying compatible accessories or alternative solutions within the same family.
Public confirmed substitute part numbers are not available in the provided documentation. Consult official Radiall resources for direct equivalents. Ensure any replacement matches the SP4T topology and 18 GHz frequency limit. Verify impedance and package compatibility before substitution.
