RF Switches Procurement Notes

Verify the specific revision status and manufacturing lot details directly with Radiall USA, Inc. or authorized distributors before procurement. Confirm that the 28Vdc latching requirement aligns with your system's power delivery capabilities. Ensure the SMA2.9 connector compatibility matches your existing cable assemblies. Request the latest datasheet to confirm any recent product change notifications or environmental compliance updates relevant to your deployment region.

RF Switches Selection Notes

Select this component when a four-port single-pole switch is required for frequencies up to 40GHz. The latching feature eliminates the need for continuous power to maintain state, which is beneficial for power-sensitive designs. Verify that the 28Vdc control voltage is compatible with your logic levels. Consider the physical dimensions of the D-sub connector and the module package to ensure adequate space within your enclosure design compared to non-latching alternatives.

RF Switches Part Context

This part belongs to the Ramses family of coaxial switches from Radiall, known for high performance in microwave applications. The Ramses series typically offers low insertion loss and high isolation across wide bandwidths. This specific model integrates latching functionality, distinguishing it from standard non-latching variants in the same frequency range. It represents a solution for robust RF switching where state retention is critical without constant energization.

RF Switches Replacement Considerations

Consult official Radiall documentation for direct cross-reference part numbers. Verify that any substitute maintains the SP4T topology, 40GHz upper limit, and SMA2.9 interface. Ensure the replacement supports the same 28Vdc latching control scheme and D-sub connector type. Do not assume compatibility with lower-voltage latching models without explicit electrical verification.
