The invention relates to a power testing device and method for a rectangular waveguide directional coupler, which belongs to the technical field of power testing and solves the problem that the prior art lacks a disclosed power testing device for realizing a rectangular waveguide directional coupler. The power test device includes a power source connected in sequence, a first directional coupler, a circulator, a directional coupler to be tested and a sliding short circuit; wherein, the first port of the circulator is connected to the output port of the first directional coupler, and the circulator The second port of the circulator is connected to the input port of the directional coupler to be measured, and the third port of the circulator is connected to the absorbing load. The acquisition of the power fluctuation range of the coupling port of the directional coupler to be measured is realized, which is simple and easy to implement, and provides technical support for the production of the directional coupler for later high-precision measurement and high-precision control applications.
Description
technical field [0001] The invention relates to the technical field of power testing, in particular to a power testing device and method for a rectangular waveguide directional coupler. Background technique [0002] The directional coupler is one of the most commonly used components in the microwave system, especially in the microwave power measurement system, it is often necessary to use the directional coupler to couple the power signal to the range that the measurement system can measure, and then measure the signal accurately and analysis. [0003] The disadvantage of the existing rectangular waveguide directional coupler is poor directivity. In some test experiments or application scenarios that require high-precision measurement of power, it cannot meet the work requirements, and there is currently a lack of public power to realize the rectangular waveguide directional coupler. test device. [0004] The power test device and method of the rectangular waveguide direct...
