Abstract

The invention relates to the technical field of microwave mode converters, and in particular relates to a high-power TE-TEM microwave mode converter which is used for solving the problems of insufficient power capacity and high manufacturing difficulty of a TE-TEM mode converter in the prior art. The high-power TE-TEM microwave mode converter comprises a central waveguide, a microwave feed-in waveguide, a microwave sliding circuit breaker, a coaxial output, a coaxial short-circuit surface and a coaxial inner conductor; the coaxial short-circuit surface comprises a centering ring installed in the coaxial inner conductor; a short-circuit surface outer conductor is installed on the centering ring; a coaxial downward-extending section is installed between the short-circuit surface outer conductor and the central waveguide; and a microwave choking coil which is not in contact with the coaxial inner conductor is installed between the coaxial downward-extending section and the short-circuit surface outer conductor. The coaxial downward extending section, the short-circuit surface outer conductor and the end face of the microwave choking coil are in contact, the electric conductivity is good, the sparking phenomenon is avoided, the power capacity of the converter can be improved, meanwhile, the converter can be divided into a plurality of parts during machining, and therefore the manufacturing difficulty is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of microwave mode converters, in particular to a high-power TE-TEM microwave mode converter. Background technique [0002] In many high-power microwave applications, it is necessary to convert the TE10 mode microwave in the rectangular waveguide to the TEM mode in the coaxial waveguide. The TE-TEM mode converters in the prior art are mainly divided into two types: antenna type and button type. . [0003] The antenna-type mode converter needs to use a dielectric coaxial waveguide. The coaxial inner conductor and antenna are fixed by the dielectric in the coaxial waveguide. The dielectric loss is high, the power capacity is small, and the inner conductor cannot be installed firmly, so it cannot be used for high-power and Occasions where force-bearing installation is required. [0004] The door-button mode converter needs to set a cylindrical or tapered step in the rectangular waveguide, which requires comple...
