OPERATING MODES OF AVALANCHE-GENERATOR DIODES OF MICROWAVE RANGE

Abstract

Construction of powerful sources of electromagnetic oscillations of microwave range is an actual task for creating modern semiconductor devices. In this paper the creation of powerful sources of electromagnetic oscillations based on reverse-biased abrupt p–n-junctions of avalanche-generator diodes (AGD) with external signal has been theoretically grounded. Classification of modes of avalanche-generator diodes has been carried out. The choice of oscillations generation mode is determined by the parameters of AGD and input signal. It is shown that coherent, multifrequency and broadband oscillations are generated in AGD. Power and spectral descriptions of oscillations of AGD are presented. The research results are of interest for the developers of powerful diode generators with the required range, power and spectral characteristics.
