Procurement Notes
This component is officially listed as obsolete by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Ensure that any available units are new and unopened, checking for original packaging integrity and date codes to mitigate risks associated with end-of-life inventory handling.
Selection Notes
Engineers selecting this part must account for its discontinued status when designing new products. The specific 10-LDFN package and electrical parameters define the footprint and biasing requirements. Alternative solutions should be evaluated based on compatible frequency ranges and interface compatibility, as direct pin-to-pin replacements may not exist for this specific Broadcom offering.
Part Context
The WS2411-BLK belongs to Broadcom's portfolio of RF power amplifiers targeting third-generation mobile communication systems. It serves as a critical component in uplink signal processing for UMTS networks. The device integrates driver stages and output matching networks into a single small outline package, reducing board space compared to discrete implementations.
Replacement Considerations
No public confirmed substitute part numbers are documented for this obsolete component. Designers must perform full re-validation if migrating to alternative RF amplifier technologies or different manufacturers' offerings.
