Procurement Notes

Verify the specific suffix (e.g., AVZ vs AVTZ) against official Ampleon documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the requested component matches the exact pinout and thermal characteristics defined in the datasheet for the SOT-1258-4 package. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure compatibility with existing board layouts and thermal management systems before procurement.

Selection Notes

Select this component for applications requiring 550 W output power at 1.8–1.9 GHz frequencies. Consider the dual N-channel structure for balanced performance in push-pull or Doherty topologies. Evaluate the 65 V breakdown voltage against system supply requirements. Assess the thermal resistance of the SOT-1258-4 package for adequate heat dissipation in the target enclosure design.
