Procurement Notes

Verify component authenticity through authorized Infineon distributors. Confirm RoHS compliance and Pb-free status prior to integration. Ensure handling precautions are strictly followed due to electrostatic discharge sensitivity. Validate package dimensions against H-36260-2 or H-37260-2 specifications as required by the specific variant.

Selection Notes

Select this component for high-power RF amplification in cellular infrastructure requiring robust thermal management. Evaluate thermal resistance characteristics relative to system cooling capabilities. Consider the integrated matching network benefits for reducing external component count. Verify compatibility with standard 30 V supply voltages and typical gate bias requirements.
