Abstract
An LDMOS power package includes a mounting substrate having a surface with one or more alignment pedestals extending therefrom. Each alignment pedestal has a mounting surface facing away from the substrate surface to provide for uniform positioning of various semiconductor elements, e.g., a transistor die or impedance matching capacitors, relative to the substrate surface. The respective pedestal mounting surfaces are preferably conductive, and are electrically coupled to the flange surface, so as to electrically couple the respective capacitor and electrode ground terminals to the flange.
