Description

Technical Field

[0001] This utility model relates to the field of dual-ridge waveguide interface conversion technology, and in particular to a dual-ridge waveguide converter. Background Technology

[0002] With the development of the communications industry, the demand for microwave and millimeter-wave devices is increasing. Waveguide converters, as key components in microwave and millimeter-wave systems, have emerged and become indispensable. Waveguide transmission is a commonly used circuit transmission structure in microwave and millimeter-wave circuit design. The biggest characteristic and advantage of waveguide structures is their high enclosure; electromagnetic wave energy is completely confined within the waveguide cavity, reducing interference between the waveguide circuit and other external circuits, and improving electromagnetic compatibility and stability. They are particularly useful for transitions or conversions between different waveguide apertures, used for measurement, testing, mode conversion, and signal transmission.

[0003] This dual-ridge waveguide converter technology is primarily used for conversion and matching between two different standard dual-ridge waveguide interfaces, WRD500D36 and WRD650D28, to achieve cross-band (C~X~Ku) coverage of 6-18GHz. However, existing technologies for transitioning or converting between different waveguide apertures, such as rectangular waveguide to rectangular waveguide, rectangular waveguide to coaxial, and dual-ridge waveguide to coaxial, are either only applicable to rectangular waveguide to rectangular waveguide or rectangular (dual-ridge) waveguide to coaxial applications. Because rectangular waveguide to rectangular waveguide conversion is limited by waveguide standards, it cannot achieve full-band broadband coverage of 6-18GHz.

[0004] Therefore, there is an urgent need to propose a dual-ridge waveguide converter with a simple structure and full-band broadband coverage. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a dual-ridge waveguide converter. The technical solution adopted by this utility model is as follows:

[0006] A dual-ridge waveguide transducer includes an integrally formed first dual-ridge waveguide connector, a transition cavity, and a second dual-ridge waveguide connector connected sequentially. A first dual-ridge waveguide port is formed on the first dual-ridge waveguide connector, a second dual-ridge waveguide port is formed on the second dual-ridge waveguide connector, and a first-stage matching waveguide cavity, a second-stage matching waveguide cavity, and a third-stage matching waveguide cavity are sequentially disposed within the transition cavity. The first-stage matching waveguide cavity is connected to the second dual-ridge waveguide port, and the third-stage matching waveguide cavity is connected to the first dual-ridge waveguide port. The interiors of the first dual-ridge waveguide port, the third-stage matching waveguide cavity, the second-stage matching waveguide cavity, the first-stage matching waveguide cavity, and the second dual-ridge waveguide port together form an H-shaped cavity. A first stepped platform is mirror-image-oppositely disposed within the first-stage matching waveguide cavity; a second stepped platform is mirror-image-oppositely disposed within the second-stage matching waveguide cavity; and a third stepped platform is mirror-image-oppositely disposed within the third-stage matching waveguide cavity. The first, second, and third stepped platforms increase in height sequentially.

[0007] Furthermore, the first step has a length of 6.98 mm, a width of 4.3 mm, and a height of 3.02 mm; the second step has a length of 7.12 mm, a width of 4.3 mm, and a height of 3.12 mm; and the third step has a length of 7.26 mm, a width of 4.34 mm, and a height of 3.26 mm.

[0008] Furthermore, the first double-ridged waveguide connector is provided with two first positioning pins; the second double-ridged waveguide connector is provided with two second positioning pins; the two first positioning pins are located diagonally opposite the first double-ridged waveguide port; the two second positioning pins are located diagonally opposite the second double-ridged waveguide port.

[0009] Furthermore, both the first and second double-ridged waveguide connectors are provided with several double-ridged waveguide connection holes.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention utilizes a stepped first, second, and third step platform, along with a third-stage matching waveguide cavity, a second-stage matching waveguide cavity, and a first-stage matching waveguide cavity for waveguide conversion. This enables transitional conversion between two different standards: a first dual-ridge waveguide port (WRD500D36) and a second dual-ridge waveguide port (WRD650D28). It fills the gap in dual-ridge waveguide interface coverage across the 6-18GHz full-band, facilitating user-end switching between dual-ridge waveguide ports. In summary, this invention offers advantages such as simple structure and full-band broadband coverage, demonstrating high practical and promotional value in the field of dual-ridge waveguide interface conversion technology.
