Abstract (in Japanese) (See Japanese page) 
(in English) Cylindrical power divider/combiner’s with broadband coaxial-conical-radial line transition have been studied, which have broadband and low loss characteristics required for the power dividing-combining systems in order to realize microwave high power solid-state amplifiers. The power divider/combiner’s is composed of the coaxial-conical-radial line transition as the central part, and the peripheral part in which the coaxial probes are line. In the transition, the coaxial line is converted via two sections of the conical lines to the radial line. The characteristic impedance of the radial line has an imaginary part, and so that the conical line of the second stage is used as a matching line such as the quarter-wavelength transformer. Therefore, the transition can be designed which have lower return loss in the wide frequency range.
The validity of the design procedure was confirmed with the experiments for the prototype twelve-way dividers.
