RF Switches Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm that the specific suffix denotes the bare die format rather than packaged variants. Check current lifecycle status as availability may be limited due to obsolescence. Ensure handling procedures account for the sensitive nature of exposed semiconductor dies during assembly.

RF Switches Selection Notes

Select this component when designing circuits requiring SPDT switching functionality at frequencies extending to 86 GHz. Consider the bare die package format if custom substrate integration is planned. Evaluate thermal management requirements given the small footprint. Compare against alternative switches if lower frequency operation suffices for cost optimization.
