Abstract
The article is devoted to the development of a scheme of a dual-band transformer of complex load impedances into a given real value of the input resistance and to the method of calculating the electrical parameters of the elements in its composition. The proposed scheme consists of two segments of single lines, supplemented by a parallel branch on the input side. To remove restrictions on the possible values of complex impedances, which are generally different in different frequency bands, the circuit can be supplemented with two additional line sections, the parameters of which are chosen arbitrarily. It can be a section for connecting the load to the circuit, as well as a section in the form of a branch from the side of the load. Verification of the proposed transformer circuit was carried out by comparing the results of its computer simulation with known results.
