RF Switches Procurement Notes

Verify availability through authorized distributors or secondary markets, as this part number is officially listed as obsolete by the manufacturer. Confirm that the specific Ramses series variant matches the required SMA termination and D-sub connector configuration. Ensure compatibility with existing 28 VDC control logic before procurement.

RF Switches Selection Notes

Select this component when an eight-port switched path is required for frequencies extending to 18 GHz. The latching feature provides state retention without continuous power consumption. Verify that the physical dimensions of the D-sub connector fit the available panel space and that the 28 VDC coil voltage aligns with the system's control supply.

RF Switches Part Context

This model belongs to the Ramses series of coaxial switches from Radiall USA, Inc. The series is characterized by precision engineering for RF applications requiring low insertion loss and high isolation. The R574423005 specifically denotes the SP8T configuration with SMA interfaces and latching functionality.

RF Switches Replacement Considerations

As the part is obsolete, direct substitutes may not be available. Evaluate other Ramses series models or comparable SP8T switches from alternative manufacturers that meet the 18 GHz frequency and 28 VDC latching requirements.

RF Switches FAQ

What is the contact form factor of the R574423005?

The component utilizes an SP8T (Single Pole Eight Throw) contact form.

Does the switch require continuous power to maintain its state?

No, it uses a latching mechanism that retains its position after the 28 VDC pulse is removed.
