The application relates to a high-power directional coupler for real-time measurement of high-power circular waveguide transmission energy. The design comprises a circular waveguide, two coupling holes and two rectangular waveguides vertically connected with the circular waveguide. High-power microwaves are transmitted in the circular waveguide, the two coupling holes are arranged on the wall surface of the circular waveguide, and the center distance is lambda / 4+n*lambda / 2 (lambda is the transmission wavelength, and n is a non-negative integer). The rectangular waveguide is vertically connected with the circular waveguide through the coupling hole, and the short side of the rectangular waveguide is parallel to the axial direction of the circular waveguide, which is used for receiving coupled energy and measuring transmission power through a power sensor. By averaging the transmission energy at the two coupling holes, the interference error caused by the echo is eliminated, and the forward transmission energy is accurately measured. The design effectively avoids the fluctuation problem in single-hole measurement, has the advantages of wide frequency band, low coupling coefficient, high reliability and high power resistance, and is suitable for real-time measurement and monitoring of high-power microwave system energy.
