Embodiment Construction
[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is further described:
[0029] Such as figure 1 and 2 , a waveguide three-way power splitter with a built-in load in this example, including a waveguide cavity and a cover plate. The cover plate covers the cavity to form three-way waveguides, which are the main waveguide and the first waveguide branch and the second waveguide branch;
[0030] For the main waveguide:
[0031] The main road waveguide is cylindrical, and the axis of the cylindrical shape is a straight line l1; the waveguide entrance of the main road waveguide and the main road waveguide outlet 16 are located at the first and last ends of the cylindrical shape;
[0032] For the first waveguide branch:
[0033] The first waveguide branch is located on the right side of the main road waveguide; the main body of the first waveguide branch is cylindrical, and the axis of the column is an arc; the first waveguide bra...

A waveguide three-way power divider with a built-in load, including a waveguide cavity and a cover plate, and the cover plate covers the cavity to form three-way waveguides, which are the main waveguide and the first and second waveguide branches; for the main waveguide: The main road waveguide is cylindrical, and the axis of the cylindrical shape is a straight line l1; the waveguide entrance and the main road waveguide outlet of the main road waveguide are located at both ends of the cylinder; for the first waveguide branch: the first waveguide branch is located at the end of the main road waveguide On the left side; the outlet of the first waveguide branch is connected to the tail end of the main body of the first waveguide branch; the first waveguide branch is in order from front to back: the first waveguide cavity, the step impedance transformation of the first load branch, the first load branch Coupling port, the first main road coupling window, the first branch road coupling window and the first branch road stepped impedance converter; the top of the first waveguide cavity is connected with the first built-in load; the first main road coupling window and the main road waveguide The middle position of is connected; the second waveguide branch and the first waveguide branch are mirror-symmetrical about the straight line l1.
Description
technical field [0001] The invention belongs to the technical field of microwave devices, and in particular relates to a waveguide three-way power splitter with a built-in carbonyl iron load. Background technique [0002] With the continuous development of microwave systems and equipment, the demand for convenience and high speed of communication is getting higher and higher. Microwave satellite communication technology is a form of communication to solve this demand. In microwave communication, the structure and working mode of the system or equipment are more and more complex, the number of channels in the system or equipment may be determined according to the actual needs, usually the number of channels is 2 N way, where N is a natural number. When encountering non-conformity 2 N If the number of channels is required, an odd number of channels may be used at this time, such as three channels, five channels, and so on. The waveguide three-way power splitter with built-i...
