Abstract

A microwave power circuit includes a thermally conductive, electrically insulating substrate such as beryllium oxide which has a relatively rough surface, a layer of dielectric material such as glass on a portion of the rough surface which layer has a relatively smooth surface, a conductive material on the relatively smooth surface, and a heat dissipating amplifying device having at least two terminals, one of which is connected to the conductive material and one of which is thermally connected to the substrate in a manner to pass heat thereto.
