VOLT-AMPERE CHARACTERISTIC AND INDUCED CURRENT IN THE EXTERNAL CIRCUIT OF AVALANCHE-GENERATOR DIODES ON THE BASIS OF THE BACK DISPLACED ABRUPT P–N-JUNCTIONS

Abstract

Creation of modern solid-state microwave power sources is based on the application of active elements with expanded functionality. The reverse-biased p–n-junctions with DC voltage are active elements of diodes generators. Avalanche-generator diodes (AGD) based on reverse-biased abrupt p–n-junctions with DC voltage are promising for creating diode generators. We investigated the static current-voltage characteristic of AGD by the methods of diffusion-drift theory. The induced current in the AGD external circuit was investigated. It was found that the spectrum of induced current is determined by the spectrum of auto oscillations of AGD. The results of the research are the theoretical basis for the creation of diode microwave generators with the requisite energy and spectral characteristics.
