“…When the impedance ratio was small the formula met the project needs. Because of the literature [4] did not achieve the desired impedance matching at any two frequency points of pure resistance load, we need to support by literature [5,6] . The literature [6] has designed a impedance converter.…”

Introduces the design method of a novel impedance transformer, proved its superiority, then optimized this new design method using optimized means, and designed the new optimized impedance transformer whose size smaller about 20 percent and bandwidth wider than the traditional stepped impedance transformer. Therefore, to simplify the design of ladder-impedance transformer and make its broadband larger and its size smaller is very meaningful for the microwave integrated circuits.

The circuit simulation of nonuniform transmission lines that were under consideration for the next generation of pettawatt-class z-pinch drivers was performed. It was confirmed that the power-transport efficiency of the designed radial transformer with an exponential impedance profile is higher than that with Gaussian profiles. Based on the Fourier's theorem and the principle of superposition, it was found that there are considerable low-frequency components for an input voltage of half-sine wave with an angular frequency of 14MRad/s. Compared to the exponential transformer, the Gaussian transformers amplify the low-frequency components to a lower extent, which makes the difference in power efficiency between the two types of the transformers. The radial transformer also serve as a passive high-pass filter and the Gaussian transformer may give better performance than that the exponential transformer does if the signal transport rather than the power transport is concerned.Index Terms-Nonuniform transmission line, Radial impedance transformer, Gaussian line, Exponential line, Z-pinch 978-1-4673-1225-7/12/$31.00 ©2012 IEEE
