Procurement Notes

Verify the component against the official Ampleon datasheet Rev. 1 dated 20 April 2017. Confirm that the package matches SOT1275-1, which is an air cavity plastic earless flanged package with six leads. Ensure compliance with Directive 2002/95/EC regarding Restriction of Hazardous Substances (RoHS). Validate all electrical parameters against the specified test conditions provided in the product data sheet.

Selection Notes

Select this component for wideband RF power amplifier designs requiring high efficiency and low memory effects. The internal matching network simplifies circuit design by reducing external component requirements. Verify that the application environment supports the required thermal management, as the device relies on a low thermal resistance path through the flange for effective heat dissipation during continuous operation.
