Design of high-power arbitrary multi-way radial power dividers using periodic matching structure

An arbitrary multi-way radial power divider/combiner with high-power capacity based on the coaxial waveguide TE 01 -mode is presented in this paper. The study of shows divider can operate base mode a large diameter, which allow waveguides to be radially distributed along circumference waveguide. equivalent circuit model used analyze its design procedure including matching section, improve transmission coefficient and isolation between output ports. To verify these, 4-way 20-way section are designed; simulation results show that capability >43 kW within 0.5 dB insertion loss for four-way divider. average value adjacent ports has improved by 11.1 after using periodic structure as well 2.78 opposite frequency range 34.08–36.32 GHz. less than 1 33.4–37.6 GHz, while return greater 25 dB.
