Abstract: In a radio frequency transistor package, a layer of metallization is deposited on an electrically insulative thermally conductive ceramic substrate member serving as a heat sink. An insular region of the metallization serves as a pad for receiving a transistor die with the collector region of the transistor bonded to the insular region of metallization. The region of the metallization surrounding the pad comprises a ground plane. An apertured ceramic insulative spacer is bonded over the ground plane metallization with the aperture in registration over the transistor. Input, output and a pair of common lead metal strips are bonded to the upper surface of the spacer in generally coplanar configuration. The two common leads extend across the spacer adjacent opposite sides of the aperture in generally tangential relation thereto. The input and output leads are disposed in between the common leads and are interrupted by the central aperture in the spacer.
