Abstract

The invention relates to the technical field of communication devices, in particular to a high-power microwave phase shifter which comprises a rectangular waveguide, a circular waveguide placed on an E face of the rectangular waveguide, and mode-converting and circular polarization units placed on other faces of the rectangular waveguide. A short-circuiting piston which can move in the direction of the axis of the circular waveguide is arranged in the circular waveguide. The mode-converting and circular polarization units are used for converting TE10 mode microwaves into two orthogonal-polarization TE11 mode microwaves which are the same in amplitude and have 90-degree phase difference, and the mode microwaves are input to the circular waveguide. Due to the fact that the high-power microwave phase shifter can achieve phase shifting without ferrite materials, the size and loss of the phase shifter can be lowered, and meanwhile the whole high-power microwave phase shifter can be made of metal materials, and accordingly high-power capacity can be achieved.

Description

technical field [0001] The invention relates to the technical field of communication devices, in particular to a high-power microwave phase shifter. Background technique [0002] High-Power Microwave (HPM for short) generally refers to strong electromagnetic radiation with a frequency between 300MHz and 300GHz and a peak power greater than 100MW or an average power greater than 1MW. The main applications of high-power microwaves include: heating controlled thermonuclear plasma through the electron cyclotron resonance mechanism; being used for high-power short-pulse radar to achieve accurate resolution of detected and tracked targets in a wide frequency band; It can transmit energy and provide energy for the spacecraft to launch into space orbit or change between orbits; it is used in high-energy particle radio frequency accelerators, high-energy physics, nuclear physics scientific research, and HPM directed energy weapons and other fields.
