Subject of the study. The subject of the work was the study of direct chaotic differentially coherent information transmission scheme based on chaotic radio pulses and its properties. The aim of the work was to carry out circuit simulation of the scheme in order to obtain its characteristics close to the characteristics of real device for the subsequent transition to experiments with physical layouts of differentially coherent transmission scheme. Methods. The circuit simulation was carried out in specialized program environment Advanced Design System (ADS). The elements of the scheme, which operation is formally clear, but their physical implementation on accessible components basis is not obvious, were selected during the process of simulation. The limitations on the frequency range and technical implementation of elements are found. Results. During the simulation in ADS the authors managed to obtain the transmission system’s operation modes, which, in general, are in qualitative agreement with previous results on the simulation of the direct chaotic differentially coherent transmission system in Matlab environment. That is additional evidence of the scheme’s performance in real conditions. Discussion. The quantitative data presented in the work are determined by the electronic components used and their actual dynamic characteristics embedded in the manufacturer’s models. They can be directly used for the preparation and conduct of experiments with physical layouts of differentially coherent transmission system.
