Procurement Notes

This component is officially discontinued and no longer manufactured by Qualcomm. Verification of availability should focus on surplus or secondary market sources rather than direct procurement from the manufacturer. Engineers must confirm the authenticity of any available units through authorized distributors or verified suppliers. Design-in activities should prioritize replacement components due to the lack of future supply assurance.

Selection Notes

Designers seeking this specific SAW filter must account for its discontinued status when planning long-term production runs. Alternative solutions should be evaluated based on similar center frequencies and package dimensions to ensure mechanical compatibility. The transition to a new component requires re-validation of RF performance characteristics, particularly insertion loss and bandwidth specifications, to maintain system integrity in WLAN applications.
