摘要：

A GW level high power combiner is investigated with theoretical analysis, numerical calculation and full wave simulation. The power combiner operates at X band, and is fed by two X-band microwave sources. To meet the requirements of power handling capacity, the overmoding ratio of the operating waveguide in the high microwave sources for combining is 12.7, which gives difficulties for the design of the combiner. This paper focuses on how to design the X band high power combiner based on overmoded waveguides, i.e., the methods for enhancing the transmission efficiency and power handling capacity, while suppressing the higher order modes. The designed power combiner has a power handing capacity higher than 5.6 GW, and its one-way transmission efficiency is above 99.0%. The power handling capacity can be further enhanced by enlarging the height of the main waveguide without any influence on the transmission efficiency.
