RF Switches Procurement Notes

Verify current availability status as the component may be obsolete or restricted. Confirm exact connector termination type and pinout compatibility with existing PCB layouts. Ensure supply chain sources provide authentic Radiall USA, Inc. products to avoid counterfeit components in critical RF environments.

RF Switches Selection Notes

Select this model when high-frequency signal routing up to 18 GHz is required in a compact form factor. The terminated Ramses architecture ensures consistent impedance matching. Verify that the 28 VDC control voltage aligns with system power supplies and that the SMA interface matches downstream interconnect requirements.

RF Switches Part Context

This part belongs to the Ramses series of coaxial switches from Radiall. The series is engineered for demanding RF applications requiring low loss and high isolation. The R574413305 specifically integrates SP3T functionality into a terminated module format, distinguishing it from non-terminated variants.

RF Switches Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires detailed electrical parameter matching and physical footprint verification against alternative SP3T coaxial switches.
