STEPPED TRANSFORMERS ON TEM-TRANSMISSION LINES

The paper presents comparative analysis of the properties of impedance stepped transformers both with monotonous and nonmonotonous step-to-s tep impedance variation, A miniature stepped transformer of a new stru cture based on a cascade of an even number of uniform transmission lin e sections has been synthesized, Section lengths are considerably shor ter than a quarter of the central wavelength, and the section impedanc es alternate, The proposed transformers are the simplest to implement among the available analogs. As an example, the results of the solutio n of the Chebyshev approximation problem for the four-and six-section transformers of different specifications are given.
