A compact broadband nonsynchronous noncommensurate impedance transformer

Nonsynchronous noncommensurate impedance transformers consist of a combination of high- and low-impedance transmission lines. High-impedance lines have narrow tracks in strip and microstrip technology, which allows for high flexibility and miniaturization of the layout in comparison to the traditional tapered line transformers. This flexibility of the broadband nonsynchronous noncommensurate impedance transformers is experimentally demonstrated in this article allowing the length reduction by almost three times. © 2012 Wiley Periodicals, Inc.
