Abstract: The master’s thesis is dedicated to the development and investigation of a three-channel power divider in the decimeter range. The development and investigation of a three-channel power divider in the decimeter range are crucial due to the needs of modern wireless communication systems. Such a divider can efficiently distribute power across three channels, which is essential for optimizing the system’s performance in the high-frequency range. It can find applications in various fields, including telecommunications, security, and wireless technologies, contributing to the improvement of productivity and reliability in wireless networks. In the first chapter, the fundamental aspects of power dividers in RF technology are discussed, including their purpose, construction principles, requirements, and applications [1]. Additionally, the methods for analyzing electrical parameters and the component base for implementing power dividers are investigated. The second chapter involves the calculation of the wave impedance of divider line segments, the study of the impact of the wave impedance of cascades on their characteristics, and the justification for the selection of the type of feeder line for the implementation of the power divider. The requirements for the accuracy of manufacturing feeder line segments are analyzed, and the use of coaxial lines with an off-center conductor is considered [3]. The third chapter is dedicated to experimental investigations of a three-channel power divider. The calculation of key electrical parameters has been performed, and the substitution scheme parameters have been determined, followed by the modeling of technical characteristics. A prototype of the experimental sample of the three-channel power divider has been implemented, and an experimental verification of the calculation results has been conducted. The work aims to improve and expand the application scope of power dividers in the decimeter range and is relevant in the context of high-frequency technology development.
