Abstract

The invention discloses a radial line waveguide high-power microwave power combiner, aiming at solving the problems that the existing power combiner needs to add a mode converter and the polarization direction of the output microwave mode must be fixed. The present invention consists of a coaxial injection waveguide, two radial line waveguide filters, and an energy synthesis output structure; the coaxial injection waveguide is composed of three transition slopes, two-stage nose cones, and two input ports; the first input port and the second A radial line waveguide filter is turned on, and the second input port is turned on with the second radial line waveguide filter; the energy synthesis output structure is composed of a Y-shaped junction and a radial line to coaxial curved waveguide, and the two radial The microwave synthesis in the line waveguide filter is transmitted to the output port. The invention can directly control the coaxial waveguide TEM mode and the circular waveguide TM of any polarization mode output by the microwave source 01 Mode for power synthesis, no additional mode converter is required, the structure is simple, and the design of large over-mode ratio of the high-frequency structure is realized.

Description

Technical field [0001] The present invention relates to power synthesizers in the field of high power microwave technologies, in particular a high power microwave channel power synthesizer based on radial line waveguide design. Background technique [0002] Currently, high power microwave (according to Benford and SWEGLE, high power microwave finger peak power is greater than 100 mW, frequency between 1 to 100 GHz) is widely used in military fields and civilized applications, these applications have high power levels A high demand is proposed; in addition, according to the high power microwave and target effect, it is sometimes necessary to synthesize high-power microwave signals having different characteristics (different waveforms, different frequencies, etc.), radiated from one output port. Using high-power microwave power synthesis technology is one of the important technical routes for implementing the above requirements, so the power synthesizer having high power capacity i...
