RF Switches Procurement Notes

Verify the specific suffix 'LP' versus 'ALP' when sourcing, as the LP variant is discontinued while the ALP version is in production. Confirm package type matches the 16-QFN specification. Check moisture sensitivity level requirements for assembly processes. Ensure supply voltage and current draw align with system design constraints before ordering.

RF Switches Selection Notes

Select this component for applications requiring wideband DC-to-6 GHz coverage with high linearity. The non-reflective design is critical for maintaining signal integrity in sensitive RF chains. Compare insertion loss and isolation metrics against alternative switches to ensure compatibility with system budget requirements and physical space limitations in compact designs.
