  • Abstract
    The advantages of using AlGaAs layers of graded Al composition to engineer the cathode of a GaAs Gunn diode are discussed. The specific target of high power operation (68 mW at room temperature) at 94 GHz over a wide range (>1.4 V) of voltage bias has been achieved. Other advantages of the cathode structure are briefly discussed.<>
