Abstract

The invention belongs to the technical field of microwave, millimeter wave and terahertz devices, and particularly relates to an ultra-wideband radial power divider based on a circular polarization TE11 mode. According to the basic principle that any linearly polarized wave can be subjected to vector decomposition into two orthogonal circularly polarized waves, a step-shaped partition plate is arranged at an input port in a circular waveguide along an output direction; the stepped partition plate is connected with the output port of the waveguide matching section and is in the same straight line with the gap between the waveguide matching sections and the gap between the input waveguides; by means of the structure that the width of the waveguide matching section is equal to the width of the gap between the waveguide matching sections, an input linear polarization TE10 mode vector is decomposed into two orthogonal circular polarization TE11 modes, the 90-degree phase difference of the orthogonal modes is achieved, and the TE11 modes show the rotating field characteristic. The rotating TE11 mode distributes electromagnetic energy to N paths of rectangular waveguides with equal power along with time, and ultra-wideband mode conversion and power distribution are realized. The device is simple in structure, easy to machine and high in conversion efficiency.

Description

technical field [0001] The invention belongs to the technical field of microwave, millimeter wave and terahertz devices, and in particular relates to an ultra-wideband radial power divider based on a circularly polarized TE11 mode. Background technique [0002] In the modern communication transmission system, the power amplifier determines the transmission output power of the system, which in turn affects the system's working distance, work efficiency and other indicators. Traditional vacuum electronic devices can output up to several hundred watts of power, but due to their large size, small bandwidth, and high processing difficulty, they are gradually replaced by solid-state semiconductor devices. In contrast, solid-state semiconductor devices have the advantages of small size, long life, low operating voltage and mass production. However, as the operating frequency increases, the output power of solid-state semiconductor devices decreases with frequency, especially in th...
