Abstract(in English) | Traveling-wave power divider/combiner's adequate for high power amplifying systems have been investigated. Multiple dividing/combiring units are successively connected in the divider/combiner. The unit consists of a rectangular waveguide section with a coaxial probe pair and a thin narrow section. In design of the units based on their equivalent circuit, frequency dependency of the admittance of individual elements in the equivalent circuit was taken into account. In addition, the length of the waveguide between the adjacent units was optimized in order to maximize isolation among the coaxial branch ports in the different units. Bandwidth for dividing power ratios deviation less than ±0.5dB was 3.3GHz, and that for -20dB return loss was wider than 5.7GHz for the designed eight-way divider operated in X-band. Furthermore, the isolation of 18dB among the branch ports was achieved. |
