Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm RoHS compliance status and specific ordering suffixes against official datasheets prior to procurement. Ensure storage conditions account for moisture sensitivity levels defined in the manufacturer documentation to prevent damage during handling and assembly processes.

Selection Notes

Select this component for designs requiring high gain and broadband performance at frequencies up to 1.0 GHz. The internal input matching reduces external component count. Verify that the 28 V operating voltage and 30 W output power align with system requirements. Consider the PowerSO-10RF package for surface mount integration and ensure thermal management solutions support the specified junction temperature limits.
