RF Switches Procurement Notes

Verify current availability status as this component may be discontinued or subject to end-of-life notices. Confirm that the 16-pin QFN package matches your PCB footprint design. Ensure control voltage levels align with your system's logic supply. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the operating temperature range meets your environmental specifications.

RF Switches Selection Notes

Select this component when non-reflective switching is critical to prevent signal interference in sensitive RF chains. The wide 100 MHz to 6 GHz bandwidth suits multi-band base station architectures. Consider the 16-pin QFN package for compact board layouts. Verify that the 1.8 dB max insertion loss fits your link budget constraints. Ensure the 42 dB isolation meets your crosstalk requirements.
