Abstract :
Optimum structure parameters of GaAs hi-lo IMPATT diodes to give a high-efficiency and a high-output power are experimentally determined in the frequency range from 7 to 18 GHz. The highest efficiency is obtained at any frequency when a diode has a punch-through factor of about 0.6 and is depleted with an electric field strength of 10 kV/cm at the end of the lo region under operation. The optimum lo-region carrier concentration to achieve the highest efficiency and the upper limit of a junction area to obtain a high-output power without decreasing efficiency are found to be simply related to frequency by the following equations: (N_{L})_{opt} = (4 \\times 10^{14}) \\cdot (f/7)^{3} cm-3and (S_{j})_{\\max } = (20 \\times 10^{-4}) \\cdot (f/10)^{-1.9}) cm2), respectively, where f is in gigahertz.
