Wideband square coaxial line power combiner

Within the presented thesis 2, 4 and 8 way power combiner structures which have a square-coaxial transmission line structure and air dielectric, operating in the 8.5-10.5 GHz frequency band, to be used for the purpose of combining high power RF power amplifiers are aimed to design and manufacture. In this study, it is aimed to realize designs that provide the transmission loss parameter, which is one of the most important parameters of power combiner structures, at the minimum level. Since air is used as the dielectric material, structures with less dielectric loss, thus less total loss compared to other power combiners, also better power handling capacity and wider operation bandwidth are obtained.
