Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm datasheet revisions and RoHS compliance details prior to integration. Check for available surplus inventory or qualified replacement alternatives as standard production may be discontinued. Ensure supply chain stability for long-term manufacturing requirements.

Selection Notes

Select this component for designs requiring broad frequency coverage up to 5 GHz with moderate power output. Consider the SOT-89-3 package constraints for thermal management given the 940 mW dissipation. Evaluate if the 19 dB gain meets system link budget requirements without excessive cascading stages.
