Reliability Prediction of AlGaAs Resonant-Tunneling Diodes and Nonlinear Converters of Microwave Radio Signals Based on Them

Abstract

Using a resonant-tunneling diode (RTD) as a nonlinear element of microwave signal converters is discussed. The research results of degradation of RTDs during the operation are given. The diffusion coefficients of Al in a resonant-tunneling structure (RTS) and of Si in near-contact zones of the RTD are determined. The structure of a diagnostic model of an RTD and the methodology of creating a reliability prediction of RTDs and nonlinear converters of microwave radio signals based on them are proposed.
