Development of Overmoded Coaxial to Two-Way Rectangular Waveguide Power Divider
摘要
Abstract
To achieve the high-efficiency mode conversion of an overmoded coaxial waveguide to a two-way rectangular waveguide in high power microwave systems,an overmoded coaxial waveguide for two-way rectangular waveguide power divider is researched.The divider uses the radial line as a mode transition structure from a coaxial waveguide to a rectangular waveguide.First,the coaxial waveguide TEM mode is divided into four rectangular waveguide TE10 modes;then the four rectangular waveguides are combined into two paths,which effectively inhibit the generation of high-order modes in the overmoded waveguide and achieve a high power-handling capacity and transmission efficiency.The design and experiment results show that at a central frequency of 2.88 GHz,the VSWR of the power divider is approximately 1.04,the corresponding transmission loss of the TEM mode to the TE10 mode is 0.15 dB,the output imbalance is approximately 0.15 dB,and the power capacity of the design is 4.52 GW,which can satisfy the needs of high-power applications.关键词
