RF Multiplexers Procurement Notes

Verify current availability status as distribution channels may list obsolete or active stock differently. Confirm that the 9-SMD lead-free package matches your PCB footprint requirements. Ensure compliance with MSL 2A handling procedures during assembly to prevent moisture damage. Cross-reference the manufacturer part number with distributor codes to avoid ordering errors due to suffix variations.

RF Multiplexers Selection Notes

Select this component when designing for the 746-756MHz and 777-787MHz frequency pairs. Consider the specified attenuation levels to ensure signal isolation meets system interference requirements. Evaluate the 9-SMD package size against available board space constraints. Verify compatibility with the intended manufacturing process for surface-mount assembly.

RF Multiplexers Part Context
