The Admittance Behavior of Low-High-Low GaAs Schottky IMPATT Diodes Academic Article uri icon


  • The admittance behavior of high-efficiency high-power low-high-low GaAs Schottky IMPATT diodes is significantly different than those of Si Read type IMPATT structures. Using small signal analysis the admittance of such low-high-low structures is investigated, and the influences of the multiplication factor, recombination current, and dielectric relaxation are included. The calculations obtained on die basis of the analysis support, in general, experimental behavior observed in such diodes. Specifically, it is observed that the order in which the cutoff and resonant frequencies occur, for such structured devices, are substantially different from those of silicon devices. © 1979 IEEE
