To solve the problem of synthesizing load matching circuits in a distributed element basis, the complex resistance of which has a non-stationary character in a wide band of operating frequencies, a new matching technique based on the sensitivity invariant apparatus in combination with the Richards and Kuroda transformation has been developed. The verification of the methodology was carried out on the example of matching the active element with the output and input loads in Mitsubishis LD-MOSRD07 power amplifiers. Radio engineering devices (RTU) are widely used in almost all spheres of human activity. In order for the RTU to provide maximum energy efficiency, and as a consequence, the maximum range of the radio line in various operating conditions, it is necessary that the elements of the radio engineering paths of both the transmitting and receiving devices, having their complex resistance (varying over time), be coordinated with each other. To perform this task, broadband matching devices (SHSU) are used, the synthesis methods of which do not take into account the variability of the load impedance caused by changes in operating conditions (temperature, vibration, various modes of operation of active elements, etc.). As a result, there is a need to develop a method for the synthesis of SHSU that provides a stable level of power transmission in conditions of varying load impedance. Such a need is relevant for RTU in both concentrated and distributed element basis. The paper proposes a method for the synthesis of matching devices for a distributed element basis. Geology is a multifaceted science that is classified into many areas, depending on the subject of research, analysis technology, subjects of study, theoretical calculations or the scope of application of knowledge obtained in the course of complex research. The most common aspects of geology as a science, their practical or applied application and benefits for humanity in modern life are described in detail below.
