Problems solved by technology

When the two waveguide cavity components are pressed tightly, due to the existence of the flatness error of the waveguide cavity components, the contact state of the two waveguide cavity components actually changes from surface contact to point contact 103, as shown in Figure 5 As shown, looking along the extending direction of the rectangular waveguide cavity 102, there is a tiny gap 104 at the junction 101 located on both sides of the rectangular waveguide cavity. This tiny gap will have a serious impact on the transmission characteristics of the rectangular waveguide cavity in the millimeter wave band, especially When the operating frequency reaches the submillimeter wave frequency band, the influence will increase sharply, and even cause the rectangular waveguide cavity to fail to work normally

Abstract

The invention discloses a high-performance combined rectangular waveguide, which comprises two waveguide cavity components. A rectangular waveguide cavity extending along the transmission direction of microwave signals is arranged at the connection of the waveguide cavity components. Next to the rectangular waveguide cavity, a first contact portion and a second contact portion are respectively provided, and the extension direction of the first contact portion and the second contact portion is the same as that of the rectangular waveguide cavity; there is at least one first contact portion, A first contact surface is formed between the first contact part and the first contact part, or another waveguide cavity component; there is at least one second contact part, between the second contact part and the second contact part, or another waveguide cavity component The second contact surface is formed between them; if the width of the first contact surface is A, the width of the second contact surface is B, and the width of the section of the rectangular waveguide cavity intercepted by the plane where the connection is located is C, then A, B, and C exist as follows Proportional relationship: 3A≤C≤7A, 3B≤C≤7B. The invention can ensure that the combined rectangular waveguide has good transmission characteristics.

Description

technical field [0001] The invention relates to a high-performance combined rectangular waveguide. Background technique [0002] There are a large number of waveguide cavity components in millimeter wave communication and test systems. For most rectangular waveguide cavity components, various circuits need to be integrated inside. In order to facilitate circuit assembly, a combined rectangular waveguide is usually required. Figure 1 to Figure 4 Several common structural forms of combined rectangular waveguides are shown. Depend on Figure 1 to Figure 4 It can be seen that the combined rectangular waveguide is composed of two waveguide cavity components, which are fixed by screws, and a rectangular waveguide cavity 102 is formed at the junction 101 of the two waveguide cavity components for transmitting microwaves. The contact area of ​​the two waveguide cavity components is Obviously larger than the cross-sectional area of ​​the rectangular waveguide cavity 102 taken by th...
