Procurement Notes

Verify component authenticity through authorized channels as the lifecycle status is listed as obsolete or limited supply. Confirm RoHS compliance details directly with the manufacturer, as sources indicate varying statuses. Ensure the specific suffix matches the required technical specifications before procurement, as availability may be restricted or subject to factory special orders.

Selection Notes

Select this component for applications requiring wideband amplification up to 5 GHz with moderate power consumption. The InGaP HBT process offers a balance between noise performance and linearity suitable for general-purpose RF stages. Consider the SOT-89 package constraints for thermal management and PCB layout when integrating into dense designs.
