The article deals with the problems of designing multi-channel high-frequency signal generators for the transceivers of unmanned aerial vehicles (UAVs). It is proposed to use high-speed digital-to-analog converters to increase the output frequency and improve the noise characteristics of UAV transceivers. The possibility of using special operating modes used in modern high-speed direct-to-analog converters (DACs) for digital generation of broadband signals is shown. Mathematical models of noise characteristics at ...

The capabilities of existing intelligent decision-making systems are very limited, so for the successful solution of a wide class of tasks based on unmanned aerial vehicles (UAVs) reliable communication with the group of aircraft is required. For communication between individual UAVs, as well as UAVs with a ground station, Flying Ad Hoc Networks (FANET) and flying sensor networks (FSN) are used. Known works devoted to the development and research of such networks consider predominantly radio communication at the p...
