Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package version and testing configuration. Confirm RoHS compliance status and check for any recent product data sheet revisions that may affect design-in parameters or legal disclaimers before finalizing procurement specifications.

Selection Notes

Select this component for asymmetrical Doherty architectures requiring high ruggedness and low thermal resistance. Ensure the application circuit accommodates the specified gate-source threshold voltage and quiescent voltage ranges. Verify impedance matching networks align with the provided load-pull data for maximum power or drain efficiency targets within the operating frequency band.

Part Context
