Procurement Notes

Verify the manufacturer origin as Ampleon Netherlands B.V., not NXP USA Inc., despite potential distributor listings. Confirm the specific package type SOT1251-2 matches your board layout requirements. Ensure handling procedures adhere to ESD sensitivity standards due to the component's classification. Check for any recent datasheet revisions that may update electrical characteristics or legal disclaimers before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring high efficiency and linearity in asymmetric Doherty configurations within the 2500 MHz to 2700 MHz band. Consider the internal matching network which simplifies RF circuit design. Evaluate thermal management capabilities given the junction-to-case thermal resistance. Verify compatibility with digital pre-distortion algorithms due to low memory effects.
