Embodiment Construction

[0020] It should be understood that the waveguide power divider of the present invention is composed of a power section, an impedance transformation section, a power dividing diaphragm, and an isolation resistor. The isolation resistance sheet is fixed in the slot window of the power dividing diaphragm, and the power subsection, the impedance transforming section and the power dividing diaphragm are assembled as a whole. The power division section and the impedance transformation section form the power division cavity, the installation position of the power division diaphragm determines the power division ratio, and the depth of the power division diaphragm into the power division cavity is used to adjust the matching and isolation. The positional relationship between the power dividing diaphragm and the impedance transformation section meets the requirements of electromagnetic field propagation and avoids the generation of high-order modes.

[0021] Therefore, the present inv...

Abstract

The invention provides a waveguide type power divider which is used for realizing arbitrary power division ratio by adopting a miniaturization and high isolation design method. The waveguide type power divider comprises a power division section, an impedance conversion section, a power division module and an isolation resistor piece. The isolation resistor piece is fixed in the slot window of the power division module. The power division section, the impedance conversion section and the power division module are integrally assembled to form a waveguide structure and an E face power division structure, so as to realize wide band power distribution. According to the miniaturized high isolation waveguide type power divider, wideband, low loss, output port isolating, simultaneous matching of ports and other performances are realized; arbitrary power division ratio design is realized; isolation among power division ports is high; and the waveguide type power divider has the advantages of simple structure, small size, high reliability, low processing difficulty and the like, and can be applied to a microwave power division network.

Description

technical field [0001] The invention belongs to the technical field of microwave networks, and relates to a waveguide power divider, in particular to a miniaturized and high-isolation waveguide power divider, which adopts a miniaturized and high-isolation design method to realize any power division ratio. Background technique [0002] The power divider is a commonly used microwave component in the microwave power division network. It is used to divide the power of the microwave signal into multiple channels according to the required ratio. There is a specific proportional relationship between the signal power of the 2-way and 2-way power division. [0003] According to the implementation method, the power divider can be divided into microstrip type, slot line type, waveguide type and so on. Compared with other forms, the waveguide type has the characteristics of simple structure, small insertion loss, and good environmental adaptability, and can be realized by simple machin...
