ABSTRACT:
A unitary device comprising a millimeter wave source embedded in a block which integrated simultaneously the bias means, the heat-dissipation means and the impedance-matching arrangements. The source, which is an avalanche diode of very small dimensions, is welded to a dissipating mounting comprising a central platform with a slight central projection. Subsequently, the diode is surrounded by a glass ring whose central opening is filled with polymerizable resin. Mechanical grinding is carried out in order to bare the top layer of the diode and metallizing performed in order to provide a supply terminal for DC. In an application of the invention to a millimeter waveguide, the supply contact is formed by a simple transverse metal wire leaving the walls of the waveguide through insulating lead-throughs.
