[0025] See also Figure 1 to Figure 3 The embodiment of the present application provides a combiner, which may include: a cavity 1, a cover plate 2, a plurality of resonant columns 3, a plurality of resonant rods 4 and a plurality of coupling structures 5, wherein a plurality of input end connectors 101 are arranged on one side of the cavity 1, and an output end connector 102 is arranged on the other side, and the cavity 1 is divided into a plurality of sub-cavities 103, and one input end connector 101 corresponds to one sub-cavity 103; the cover plate 2 is arranged on the cavity 1; a plurality of resonant columns 3 are arranged in each sub-cavity 103; a plurality of resonant rods 4 are arranged on a side of the cover plate 2 facing the cavity 1, and the resonant rods 4 correspond to the resonant columns 3 one by one; a plurality of coupling structures 5 are arranged in the cavity 1 and are located between two adjacent resonant columns 3, wherein the coupling structure 5 is used to adjust the signal coupling effect in the corresponding sub-cavity 103 by changing the distance between itself and the two adjacent resonant columns 3.

[0026] In this embodiment, the cavity 1 is the main body of the entire combiner, and the cavity 1 is divided into a plurality of sub-cavities 103. A plurality of input-end connectors 101 are arranged on one side of the cavity 1 for connecting a plurality of input signal sources. An output-end connector 102 is arranged on the other side of the cavity 1 for outputting the combined signal. A plurality of resonant columns 3 are arranged in each sub-cavity 103 for processing the corresponding input signals. The cover plate 2 is arranged on the cavity 1 to close the cavity 1 and form a complete internal space. Its main function is to protect the internal components and provide a position for installing the resonant rod 4. A plurality of resonant columns 3 are arranged in the corresponding sub-cavities 103. The resonant column 3 is a key component in the combiner and is used to generate resonance of a specific frequency, thereby selectively passing or suppressing certain frequency signals. The number of resonant columns 3 in each sub-cavity 103 may be different. A plurality of resonant rods 4 are arranged on the side of the cover plate 2 facing the cavity 1. The resonant rods 4 are usually used to fine-tune the resonant frequency to ensure the best working performance. In the present application, when debugging the combiner, it is only necessary to adjust the lateral distance between the coupling structure 5 and the corresponding resonant column 3 to debug the combiner. This method of debugging the combiner is simple and reliable, enhances the stability of the combiner debugging, has high production efficiency and low production cost.

[0027] like Figure 1 As shown, the resonant column 3 is a hollow structure. When the cover plate 2 is matched with the cavity 1, the resonant rod 4 enters the hollow cavity of the resonant column 3 to form a resonant cavity. The signal entering the cavity 1 is reflected and accumulates energy in the resonant cavity to form a resonance, thereby selectively enhancing or suppressing specific frequency components in the signal. It should be understood that the purpose of tuning the combiner is to enhance the signal of a specific component (the signal of the target frequency band) in the signal and suppress the signal of other frequency components.

[0028] In combination with the embodiment of the present application, the coupling structure 5 is located between two adjacent resonant columns 3, and the distance between the coupling structure 5 and the adjacent resonant columns 3 can be adjusted. Therefore, the resonant frequency and mode of the resonant column 3 for the signal can be changed by adjusting the distance between the coupling structure 5 and the adjacent resonant column 3, so that the frequency range, insertion loss, standing wave ratio and out-of-band suppression and other parameters of the resonant cavity can be adjusted, so as to ultimately enhance the specific frequency signal and suppress the signals of other frequency components, thereby achieving the purpose of debugging the signal.

[0029] Furthermore, in the embodiment of the present application, each resonant rod 4 can be adjusted first according to the simulation results so that each resonant rod 4 reaches the target depth, thereby achieving coarse adjustment of the combiner; then, the coupling structure 5 is adjusted to further adjust the resonant frequency of the resonant cavity to achieve fine adjustment of the combiner. Finally, the combiner meets the technical requirements. Compared with the prior art, the combiner of the present application does not need to repeatedly adjust a large number of resonant rods 4, but only needs to adjust a small number of coupling structures 5 to achieve fine adjustment, thereby greatly reducing the difficulty of debugging and simplifying the debugging process.

[0030] The working principle of the combiner involved above is: multiple input signals enter the corresponding sub-cavity 103 through their respective input end connectors 101, and the resonant column 3 in each sub-cavity 103 processes the input signal, selectively passes or suppresses the signal of a specific frequency, and further reselects the signal component through the coupling structure 5, so that the combiner finally meets the parameter performance requirements. The signals in the multiple sub-cavities 103 are finally combined into one output from the output end connector 102. During the entire process of debugging the combiner, all the resonant columns 3 and coupling structures 5 are pre-optimized to ensure the consistency and stability of each combiner.

[0031] The structure and working principle of the combiner provided in the present application are further introduced below in conjunction with the accompanying drawings.

[0032] See also Figure 4 The coupling structure 5 may include: an adjusting screw 501, a first matching portion 502, a second matching portion 503, an adjusting assembly and two coupling disks 504, wherein one end of the adjusting screw 501 is arranged in the cavity 1; the first matching portion 502 is rotatably matched with the adjusting screw 501; the second matching portion 503 is threadedly matched with the adjusting screw 501; the adjusting assembly is arranged between the first matching portion 502 and the second matching portion 503 and has a telescopic freedom in a first direction, and the adjusting assembly has a first telescopic end and a second telescopic end opposite to each other in the first direction, and the first direction intersects with the extension direction of the adjusting screw 501; the two coupling disks 504 are correspondingly hinged to the two telescopic ends of the adjusting assembly and are arranged opposite to each other in the first direction.

[0033] Specifically, when debugging the combiner, the adjusting screw 501 is turned, and the adjusting screw 501 starts to rotate. Since the first matching portion 502 is rotationally matched with the adjusting screw 501, the position of the first matching portion 502 remains unchanged when the adjusting screw 501 rotates. Since the second matching portion 503 and the adjusting screw 501 are threadedly matched, when the adjusting screw 501 rotates, the second matching portion 503 moves toward or away from the first matching portion 502. Specifically, when the adjusting screw 501 rotates clockwise, the second matching portion 503 moves toward the first matching portion 502; when the adjusting screw 501 rotates counterclockwise, the second matching portion 503 moves away from the first matching portion 502.

[0034] like Figure 4 As shown, the first direction is the X direction in the figure, and the extension direction of the adjusting screw 501 is the Y direction in the figure. The first direction intersects with the extension direction of the adjusting screw 501, and can be specifically perpendicular to the extension direction of the adjusting screw 501. Because the adjusting component has the telescopic freedom in the first direction, that is, the first telescopic end and the second telescopic end of the adjusting component can be close to or away from each other in the first direction. Specifically, when the second matching portion 503 moves in the direction close to the first matching portion 502, the first telescopic end and the second telescopic end in the adjusting component move away from each other in the first direction, so that the two coupling disks 504 move in the direction away from each other, thereby reducing the distance between the two coupling disks 504 and the corresponding resonant column 3; when the second matching portion 503 moves in the direction away from the first matching portion 502, the first telescopic end and the second telescopic end in the adjusting component move close to each other in the first direction, and the two coupling disks 504 move in the direction close to each other, thereby increasing the distance between the two coupling disks 504 and the corresponding resonant column 3.

[0035] like Figure 4 As shown, in this exemplary embodiment, the distance between the coupling structure 5 and the adjacent resonant column 3 changes, specifically refers to: the distance between the coupling disk 504 and the adjacent resonant column 3 changes, that is, this exemplary embodiment specifically aims to change the resonant frequency of the resonant cavity (formed by the resonant column 3 and the resonant rod 4) for the signal by changing the distance between the coupling disk 504 and the adjacent resonant column 3, thereby achieving the purpose of coupling and adjusting the signal entering the combiner cavity 1.

[0036] It can be seen that in the process of adjusting the adjusting screw 501, the adjusting screw 501 drives the first telescopic end and the second telescopic end in the adjusting component to change the distance in the first direction, thereby driving the distance between the two coupling disks 504 to change, that is, the spacing between the coupling disk 504 and the resonant column 3 adjacent thereto changes. Therefore, the combiner provided by the present application can complete the coarse adjustment of the combiner by first adjusting the resonant rod 4, and then adjust the adjustment component to adjust the distance between the coupling disk 504 and the resonant column 3, thereby achieving fine adjustment of the combiner, without having to debug multiple resonant rods 4 one by one, thereby greatly simplifying the debugging complexity of the combiner, reducing the uncertainty and instability in the debugging process, and having a simple structure, high production efficiency, and low production cost.

[0037] like Figure 4 As shown, in an exemplary embodiment, a groove extending along a third direction is provided on the side of the coupling disk 504 facing the adjusting screw 501, and the recessed depth of the groove and the width in the second direction are both greater than the diameter of the adjusting screw 501, the third direction is the same as the extension direction of the adjusting screw 501, and the second direction intersects with the third direction and the first direction.

[0038] Specifically, the third direction is the Z direction in the figure. In a preferred embodiment, the first direction, the second direction and the third direction can form a spatial orthogonal system. A groove is provided on the side of the coupling disk 504 close to the adjusting screw 501. By providing the groove on the coupling disk 504, when the two coupling disks 504 move away from each other, the entire structure is not greatly affected. However, when the two coupling disks 504 move toward each other, the existence of the adjusting screw 501 will block the further movement of the two coupling disks 504. For this reason, grooves are provided on the side of the two coupling disks 504 facing the adjusting screw 501, which can avoid the adjusting screw 501 and make the adjustable distance between the two coupling disks 504 larger, so that the debugging range of the combiner can be wider based on the coupling structure 5.

[0039] Continue to refer Figure 4 In the exemplary embodiment, two groups of adjustment components are specifically provided, and the two groups of adjustment components are arranged opposite to each other in the second direction. By providing two groups of adjustment components on both sides of the coupling disk 504 to support the coupling disk 504 respectively, the support stability of the coupling disk 504 can be improved, thereby improving the stability and durability of the coupling structure 5 as a whole.

[0040] It is worth noting that in the embodiment of the present application, the first matching part 502, the second matching part 503 and the adjustment component can all be non-metallic materials, while the adjustment screw 501 and the coupling disk 504 can both be metal materials. Among them, the coupling disk 504 is made of metal material, so that when the distance between it and the resonant column 3 changes, it can affect the resonant frequency of the resonant cavity for the signal. In some embodiments, the surface of the coupling disk 504 is provided with a silver-plated material layer, which can significantly reduce the resistance of passive devices and reduce energy loss during signal transmission, thereby improving the efficiency and performance of the overall circuit; reducing signal reflection and interference, and improving signal transmission quality and stability.

[0041] Of course, in other embodiments, the first matching portion 502, the second matching portion 503 and the adjusting screw 501 may all be made of metal materials or partially be made of metal materials, which all fall within the protection scope of the present application.

[0042] Please continue reading Figure 4 The adjustment component may include: four coupling rods 505, wherein the four coupling rods 505 are hinged end to end to form a diamond structure, and the four coupling rods 505 include two first coupling rods and two second coupling rods, the first ends of the two first coupling rods are hinged to the first matching portion 502, and the first ends of the two second coupling rods are hinged to the second matching portion 503; the second ends of the two first coupling rods are correspondingly hinged to the second ends of the two second coupling rods to form a first telescopic end and a second telescopic end.

[0043] Among them, in this embodiment, the adjustment component is configured as four coupling rods 505 hinged end to end. The advantage of this configuration is that when the second matching portion 503 moves up and down (in the Y direction in the figure) on the adjustment screw 501, it can easily drive the two coupling disks 504 to move closer to the corresponding resonant column 3 or away from the corresponding resonant column 3, thereby realizing the debugging of the combiner.

[0044] Specifically, four coupling rods 505 hinged end to end can be arranged on both sides of the two coupling discs 504, which play the role of connecting the two coupling discs 504 together, and can move with the movement of the coupling rods 505, and at the same time make the first matching part 502 and the second matching part 503 work in conjunction. By adjusting the shape of the diamond structure, the coupling effect can be flexibly changed to adapt to different working conditions and requirements. By accurately controlling the position of the coupling rods 505, the performance of each combiner can be ensured to be consistent.

[0045] Please continue reading Figure 4 One end of the adjusting screw 501 extends out of the cover plate 2 , and the portion of the adjusting screw 501 extending out of the cover plate 2 is threadedly matched with a first locking nut 506 and a second locking nut 507 in sequence.

[0046] Specifically, the arrangement of the first locking nut 506 and the second locking nut 507 ensures that the positional relationship of each component remains stable after the combiner is debugged. Specifically, the first locking nut 506 locks the first matching portion 502; the second locking nut 507 locks the adjustment screw 501. During the specific assembly, the first matching portion 502 is first rotated to match the adjustment screw 501, and then the first locking nut 506 is screwed to lock the first matching portion 502, and then the second locking nut 507 is screwed to fit with the first locking nut 506 to achieve the limit of the adjustment screw 501.

[0047] It should be noted that a matching hole is provided at the end of the adjusting screw 501, and the function of the matching hole is to facilitate the screwing of the adjusting screw 501. When the adjusting screw 501 needs to be screwed, the second locking nut 507 needs to be removed from the adjusting screw 501 first, and then the adjusting screw 501 is screwed to adjust the distance between the two coupling disks 504 and complete the debugging of the combiner.

[0048] See also Figure 4 A plurality of blind holes are provided on the cavity 1, the number of the blind holes is the same as the number of the adjusting screws 501, and the plurality of blind holes correspond to the plurality of adjusting screws 501 one by one, and the end of each adjusting screw 501 is slidably fitted in the corresponding blind hole.

[0049] In this embodiment, the provision of multiple blind holes enables the adjusting screw 501 to fit into the cavity 1, and the end of each adjusting screw 501 slides and fits into the corresponding blind hole, so that the adjusting screw 501 can rotate freely in the blind hole without hindrance. Specifically, through the design of the blind hole, a fixed point is provided, so that the adjusting screw 501 can rotate along the blind hole, thereby changing the position of the adjusting component. When debugging the combiner, the adjusting screw 501 can be rotated in the blind hole by rotating it. During the rotation of the adjusting screw 501, the coupling rod 505 will be pushed or pulled, thereby changing the shape of the diamond structure. Changing the shape of the diamond structure will affect the relative position between adjacent resonant columns 3, thereby changing the coupling effect.

[0050] Furthermore, the position where the adjusting screw 501 cooperates with the blind hole can be set as the optical axis, and this section of the optical axis slidably cooperates with the hole wall of the blind hole. In this way, when the adjusting screw 501 is turned to debug the combiner, the resistance caused by friction between the blind hole and the adjusting screw 501 can be effectively reduced.

[0051] See also Figure 1 , Figure 2 Two input end connectors 101 are provided on one side of the cavity 1 , and one output end connector 102 is provided on the other side. The cavity 1 is divided into two sub-cavities 103 .

[0052] In this embodiment, the combiner is set to have two inlet ports and one outlet port. Accordingly, the cavity 1 is divided into two sub-cavities 103. Compared with the traditional combiner, when debugging, it is necessary to specifically adjust the distance between each resonant column 3 and the corresponding resonant rod 4 to realize the debugging of the combiner. In this application, it is only necessary to adjust the distance between the coupling structure 5 and the two adjacent resonant columns 3 to realize the debugging of the combiner. The debugging method is simple and reliable, and does not require more complicated operations.

[0053] When the combiner involved in this embodiment is working, two different input signals enter the corresponding sub-cavity 103 through their respective input end connectors 101, and the resonant column 3 in each sub-cavity 103 processes the input signal, selectively passing or suppressing signals of specific frequencies. The signals between different sub-cavities 103 are properly coupled and combined through the coupling structure 5. Finally, the combined signal is output from the output end connector 102. Through this design, the workload of manually adjusting multiple resonant rods 4 to penetrate into the resonant column 3 is reduced, and the reliability and long-term stability of the equipment are improved.

[0054] It should be noted that, according to different working requirements, one side of the cavity 1 may be provided with three or more input end connectors 101, and the other side may be provided with one output end connector 102. Accordingly, the cavity 1 is divided into three or more sub-cavities 103.

[0055] See also Figure 2 Three coupling structures 5 are arranged in the first sub-cavity 103 , and the three coupling structures 5 are respectively located between two adjacent resonant columns 3 ; two coupling structures 5 are arranged in the second sub-cavity 103 , and the two coupling structures 5 are respectively located between two adjacent resonant columns 3 .

[0056] Specifically, three coupling structures 5 are arranged in the first sub-cavity 103 and two coupling structures 5 are arranged in the second sub-cavity 103, which can fully meet the debugging of the combiner with two input end connectors 101 and greatly simplify the debugging steps of the combiner.

[0057] In addition, the three coupling structures 5 in the first sub-cavity 103 are arranged between any two adjacent resonant columns 3; similarly, the two coupling structures 5 in the second sub-cavity 103 are also arranged between any two adjacent resonant columns 3. Such an arrangement will not affect the debugging of the combiner.

[0058] See also Figure 1 The cavity 1 and the cover plate 2 are fixedly connected by bolts.

[0059] Among them, the cavity 1 and the cover plate 2 are fixedly connected by bolts, and disassembly and assembly are convenient on the basis of reliable connection. Specifically, a threaded hole is opened at the end face of the cavity 1, and a threaded hole is also opened on the partition protrusion of the sub-cavity 103. At the same time, through matching holes are opened at positions corresponding to these threaded holes on the cover plate 2. When assembling, it is only necessary to snap the cover plate 2 onto the top of the cavity 1 so that the matching holes on the cover plate 2 are aligned with the threaded holes on the cavity 1, and then fix the cover plate 2 to the cavity 1 by bolts, thereby completing the assembly of the combiner. It should be noted that a plurality of coupling structure matching holes are also opened on the cover plate 2, and some components of the coupling structure 5 pass through the cover plate 2 and are fixed in the corresponding coupling structure matching holes.

[0060] See also Figure 2 , the distance between two adjacent resonant columns 3 is equal.

[0061] In this embodiment, the equal spacing between two adjacent resonant columns 3 is conducive to installing the coupling structure 5 between the two resonant columns 3 and is easy to manufacture. In addition, the equal spacing between two adjacent resonant columns 3 ensures that the coupling and interaction between each resonant column 3 are uniform and controllable. Equal spacing ensures that the working environment of each resonant column 3 is consistent, thereby improving the consistency of the performance of the entire combiner. This consistency is particularly important for the merging of multi-channel signals, and can ensure that the signal processing effect of each channel is the same. Uniform spacing makes the coupling effect between adjacent resonant columns 3 more controllable and predictable, which helps to optimize signal transmission and interference suppression. By adjusting the spacing between the resonant column 3 and the coupling structure 5, the coupling effect can be adjusted, thereby affecting the bandwidth and frequency response characteristics of the combiner. The equal spacing between the resonant columns 3 effectively simplifies the design process, reduces the variables that need to be considered, and makes the design and manufacturing simpler and more efficient. During the production and assembly process, it is easier to perform quality control and reduce the performance differences caused by inconsistent spacing between the resonant columns 3. If more resonant columns 3 need to be added to support more input terminal connectors 101, the design can be expanded by simply copying the existing spacing without recalculating the new spacing. This extended design enables the combiner to adapt to different numbers of input signals and has better flexibility. In addition, the equal spacing design between two adjacent resonant columns 3 reduces mechanical stress and electromagnetic interference caused by asymmetric or uneven distribution, thereby improving the long-term stability and reliability of the combiner.

[0062] See also Figure 2 , nine resonant columns 3 are evenly arranged in the first sub-cavity 103 , and ten resonant columns 3 are evenly arranged in the second sub-cavity 103 .

[0063] Among them, for the combiner with two input end connectors 101 , according to the size of its cross section, nine resonant columns 3 can be arranged in the first sub-cavity 103 , and ten resonant columns 3 can be arranged in the second sub-cavity 103 .

[0064] Different numbers of resonant columns 3 can be optimized for different frequency ranges. Nine resonant columns 3 are suitable for a narrower frequency range, while ten resonant columns 3 are suitable for a wider frequency range. This design can adjust the number of resonant columns 3 according to the specific characteristics of the input signal to achieve the best performance. By setting different numbers of resonant columns 3 in different sub-cavities 103, it is possible to flexibly adapt to various application requirements and improve the versatility and applicability of the combiner. By adjusting the number of resonant columns 3, the coupling effect between adjacent resonant columns 3 can be better controlled, thereby optimizing the overall performance. Different numbers of resonant columns 3 help reduce mutual interference between different input signals and improve the purity and stability of the signal. In addition, although the number of resonant columns 3 in each sub-cavity 103 is different, the evenly distributed design makes the debugging process simpler because only the specific parameters in each sub-cavity 103 need to be focused on.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
