RF Switches Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging options such as tape and reel or cut tape. Review product change notices for any recent manufacturing updates. Ensure storage conditions align with semiconductor handling standards to maintain performance integrity prior to assembly.

RF Switches Selection Notes

Select this component when a compact SPDT switch is required for frequencies up to 2.5 GHz. Consider the 6-DFN footprint for space-constrained designs. Evaluate the 0.55 dB insertion loss against system link budget requirements. Verify that the 18 dB isolation meets interference rejection needs. Ensure the 3V control logic compatibility matches the host controller interface.
