[0047] Wireless communication technology is developing rapidly in the industrial and consumer electronics industries, and a variety of high-performance microwave devices are in great demand. In modern wireless communication systems and indoor distributed communication systems, balanced circuits are widely used due to their high immunity to environmental noise, electromagnetic interference, etc. Among them, balanced bandpass filters have been well studied. On the other hand, jumpers have been widely used in multi-channel systems. In order to achieve size reduction and simplify circuit design, cavity filter jumpers as functional integrated devices have become a feasible method to meet the design requirements of balanced RF front-end systems and multi-channel systems. Cavity filter jumpers have been extensively studied, including various implementation forms. However, the existing devices are difficult to meet the indoor application scenarios that require low loss, high power handling capability and high no-load quality factor.

[0048] Cavity filter jumpers based on traditional transmission structure design usually face challenges such as high loss, low power handling capability, and low Qu value, making it difficult to adapt to the development trend of multi-standard, multi-band high-frequency wireless communication systems.

[0049] Based on the above technical problems, an embodiment of the present application provides a cavity filter jumper. In this technical solution, the cavity filter jumper provided by the present application includes a common resonant component and multiple groups of resonant components, the common resonant component is provided with a common cavity; the resonant component includes multiple first elements and multiple second elements; the first element is provided with a first cavity, the first cavity is connected to the common cavity, the first cavities of the multiple first elements are connected to each other, and the first element is provided with a first connecting end; the second element is provided with a second cavity, the second cavity is connected to the common cavity, the second cavities of the multiple second elements are connected to each other, and the second element is provided with a second connecting end; in the same resonant component, the first cavity of the first element can be connected to the second cavity of the second element through the common cavity.

[0050] With such arrangement, the first connection end on each first element of the cavity filter jumper can be used as a signal input end, and the second connection end on each second element can be used as a signal output end. In the same resonant component, since there are multiple signal input ends and signal output ends, the signal has the effect of differential transmission during transmission, and the cross-transmission of several channel signals and the isolation function between the transmission channels of different resonant components are integrated into a relatively compact structure. Since the first cavity of each resonant component is connected to the common cavity, and the cavity connection between different components can be achieved through the common cavity, this reasonable structural layout is conducive to optimizing the signal transmission path and reducing the loss and distortion of the signal during transmission. The common resonant component and the mutually independent first cavity and second cavity play a role of shielding and isolation to a certain extent, preventing the crosstalk of signals between different channels, improving the anti-interference ability of the cavity filter jumper, and further improving the overall performance of the cavity filter jumper.

[0051] The shared resonant component and interconnected cavity design in this solution avoid unnecessary repeated structures, further optimize the overall size, make it more adaptable to the development trend of miniaturization, and are conducive to the miniaturization and integration goals of cavity filter jumpers.

[0052] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0053] Reference Figure 1 , Figure 2 and Figure 3 As shown, a cavity filter jumper provided in an embodiment of the present application includes a common resonant component 100 and a plurality of groups of resonant components 200 , and the common resonant component 100 is provided with a common cavity.

[0054] The resonant component 200 includes a plurality of first elements 210 and a plurality of second elements 220 ; the first element 210 is provided with a first cavity, the first cavity is connected to a common cavity, the first cavities of the plurality of first elements 210 are connected to each other, and the first element 210 is provided with a first connecting end 300 .

[0055] The second element 220 is provided with a second cavity, the second cavity is communicated with the common cavity, the second cavities of the plurality of second elements 220 are communicated with each other, and the second element 220 is provided with a second connecting end 400 .

[0056] In the same resonant component 200 , the first cavity of the first element 210 can communicate with the second cavity of the second element 220 through the common cavity.

[0057] In the above embodiment, by setting the structural form of the common resonant element 100 and multiple groups of resonant components 200, more functional components can be integrated in a limited space compared to the traditional structural design. The design of the common cavity allows each resonant component 200 to be arranged around it, reducing the overall occupied space, helping to achieve the miniaturization of the cavity filter jumper, and meeting the miniaturization requirements of wireless communication technology in the industrial and consumer electronics industries. The common resonant element 100 and the interconnected cavity design in this solution avoid unnecessary repeated structures, further optimize the overall size, and make it more adaptable to the development trend of miniaturization.

[0058] In this way, the first connection end 300 on each first element 210 of the cavity filter jumper can be used as a signal input end, and the second connection end 400 on each second element 220 can be used as a signal output end. In the same resonant component 200, since there are multiple signal input ends and signal output ends, the signal has a differential transmission effect during transmission, and the cross transmission of several channel signals and the isolation function between the transmission channels of different resonant components 200 are integrated in a relatively compact structure. Since the first cavity of each resonant component 200 is connected to the common cavity, and the cavity connection between different components can be achieved through the common cavity, this reasonable structural layout is conducive to optimizing the signal transmission path and reducing the loss and distortion of the signal during transmission. The common resonant element 100 and the mutually independent first cavity and second cavity play a shielding and isolation role to a certain extent, prevent the crosstalk of signals between different channels, improve the anti-interference ability of the cavity filter jumper, and further improve the overall performance of the cavity filter jumper.

[0059] In a possible implementation manner, in the same resonant component 200 , the number of the first elements 210 is two.

[0060] The first element 210 has a first hemispherical surface 211 and a first plane 212 , and the first hemispherical surfaces 211 of the two first elements 210 are close to each other.

[0061] In the same resonant component 200 , the number of the second elements 220 is two.

[0062] The second element 220 has a second hemispherical surface 221 and a second plane 222 , and the second hemispherical surfaces 221 of the two second elements 220 are close to each other.

[0063] In the above embodiments, in order to achieve the goal of miniaturization and integration, the waveguide cavity device has the advantages of low insertion loss and high quality factor (Qu) value, and has unique advantages in the high frequency band, and has been widely studied in the related art. However, the research and design of the cavity filter jumper based on the waveguide structure is not sufficient. Compared with the rectangular and cylindrical metal waveguide resonant cavity, the spherical resonant cavity has a higher Qu value. The hemispherical resonant cavity inherits the advantages of the spherical resonant cavity and has many degenerate modes, which can be used to design a balanced cavity filter jumper. And the hemispherical shape reduces the volume by half compared to the spherical shape, which is easy to further achieve miniaturization. By designing the first element 210 as a structure having a first hemispherical surface 211 and a first plane 212 and the first hemispherical surfaces 211 of the two first elements 210 are close to each other, and the second element 220 is designed to have a second hemispherical surface 221 and a second plane 222 and the second hemispherical surfaces 221 of the two second elements 220 are close to each other, the components can be more reasonably arranged in a limited space.

[0064] This design of the first element 210 and the second element 220 in a hemispherical form achieves a compact layout, significantly reduces unnecessary spacing and gaps, and thus effectively reduces the space occupied by the entire cavity filter jumper, which helps to achieve miniaturization of the equipment and meet the demand for miniaturization of wireless communication technology in the industrial and consumer electronics industries.

[0065] The structure in which the first hemispherical surfaces 211 of the first element 210 are close to each other and the second hemispherical surfaces 221 of the second element 220 are close to each other makes the signal distribution inside the resonant component 200 more uniform and stable. This helps to improve the electromagnetic characteristics of the cavity filter jumper, such as reducing loss and improving selectivity, thereby improving the performance of the cavity filter jumper and better meeting the requirements of the wireless communication system for high-performance microwave devices. The performance indicators of the cavity filter jumper, such as the resonant frequency, bandwidth, isolation, etc., can be accurately controlled by adjusting the parameters such as the hemispherical radius, plane size and relative position between the first element 210 and the second element 220, so as to better meet the specific needs of different application scenarios, further expanding the application scope and performance advantages of the cavity filter jumper.

[0066] In a possible implementation manner, in the same resonant component 200 , the first planes 212 of the two first elements 210 are far away from each other and parallel to each other.

[0067] And / or, in the same resonant component 200 , the second planes 222 of the two second elements 220 are far away from each other and parallel to each other.

[0068] In the above embodiment, by making the first planes 212 of the two first elements 210 far away from each other and parallel to each other, and the second planes 222 of the two second elements 220 far away from each other and parallel to each other, the arrangement of the first elements 210 and the second elements 220 in space can be changed to a certain extent, making them more regular and orderly. This layout can more effectively utilize space, reduce the ineffective gaps between the elements, and thus reduce the overall size of the cavity filter jumper.

[0069] In addition, such an arrangement can make the signal transmission path inside the resonant component 200 clearer and simpler. The first planes 212 of the two first elements 210 are far away from each other and parallel to each other, and the second planes 222 of the two second elements 220 are far away from each other and parallel to each other, which facilitates circuit wiring and connection in the same layer, reduces the complexity of cross-layer connection, thereby enhancing the circuit integration of the cavity filter jumper and better adapting to the development trend of highly integrated modern electronic equipment.

[0070] In a possible implementation, the two first elements 210 and the two second elements 220 in the same resonant component 200 are connected via different first connecting membranes 500. In a specific implementation, the first connecting membrane 500 can be set to be cylindrical, and the cylindrical first connecting membrane 500 is easier to transmit energy and has less energy loss, so that the cavity filter jumper has better performance.

[0071] In a possible implementation manner, the first connection end 300 is located on the first hemispherical surface 211 . In the same resonant component 200 , the first connection end 300 is located between two first planes 212 .

[0072] And / or, the second connecting end 400 is located on the second hemispherical surface 221 , and in the same resonant component 200 , the second connecting end 400 is located between two second planes 222 .

[0073] In the above embodiment, the first connection end 300 and the second connection end 400 are respectively defined on the first hemispherical surface 211 and the second hemispherical surface 221, and are located between the corresponding two first planes 212 and the two second planes 222, so that the spatial distribution of each first element 210 and the second element 220 in the resonant component 200 is more orderly and compact. In this way, the space occupied by the entire cavity filter jumper can be reduced, which helps to achieve miniaturization of the device.

[0074] In a possible implementation, in the same resonant component 200 , a line connecting the first connection end 300 and the second connection end 400 passes through a common resonant element 100 .

[0075] In the above embodiment, by allowing the connection line of the first connection end 300 and the second connection end 400 to pass through the common resonant element 100, the space required for the additional connection path is reduced, so that the entire cavity filter jumper is more streamlined in structure, which helps to reduce its overall size and realize more functional integration in a limited space. The precise position of the first connection end 300 and the second connection end 400 helps to shorten the signal transmission path and reduce the adverse effects of reflection, scattering and other adverse effects of the signal during the transmission process, so that the signal can be transmitted more quickly and accurately in the resonant component 200, thereby improving the signal transmission quality of the cavity filter jumper.

[0076] When implementing it, continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, the same first connection end 300 includes a first coaxial probe 310 and a first coaxial feeding connector 320, the first coaxial feeding connector 320 is connected to the first coaxial probe 310, and a portion of the first coaxial probe 310 is inserted into the corresponding first element 210; the same second connection end 400 includes a second coaxial probe 410 and a second coaxial feeding connector 420, the second coaxial feeding connector 420 is connected to the second coaxial probe 410, and a portion of the second coaxial probe 410 is inserted into the corresponding second element 220.

[0077] The first coaxial probe 310 of the first connection end 300 on one of the first elements 210 in the same resonant component 200 is collinear with the second coaxial probe 410 of the second connection end 400 on the second element 220 in the same layer, and the first connection ends 300 on the two first elements 210 in the same resonant component 200 are arranged in parallel and in the same plane.

[0078] The interval between the two first coaxial probes 310 on the two first elements 210 in the same resonant component 200 is set to H, and the depth of the first coaxial probe 310 inserted into the first element 210 and the depth of the second coaxial probe 410 inserted into the second element 220 are set to L. By adjusting the sizes of H and L, the coupling between the first connecting end 300 and the first element 210 and the second connecting end 400 and the second element 220 can be controlled. By adjusting H and L to appropriate sizes, good return loss can be achieved, thereby reducing the overall loss of the cavity filter jumper.

[0079] In a possible implementation, in the arrangement direction of the plurality of first elements 210 in the same resonant component 200 , the first portion of the first elements 210 and the first portion of the second elements 220 are arranged in the same layer, and the second portion of the first elements 210 and the second portion of the second elements 220 are arranged in the same layer.

[0080] In the above embodiment, this layered same-layer arrangement can make full use of the space of the cavity filter jumper. By reasonably arranging the layers of the first element 210 and the second element 220 in the vertical direction, the waste of space is avoided, and the size of the cavity filter jumper in all directions can be made more balanced and compact, so that the entire cavity filter jumper can accommodate more functional elements in a smaller space, which helps to achieve the miniaturization of the device. And in this way, the signal is more uniform and stable when it is transmitted inside the cavity filter jumper. In the case where the first element 210 of the first part and the second element 220 of the first part are arranged on the same layer, and the first element 210 of the second part and the second element 220 of the second part are arranged on the same layer, the electromagnetic coupling between the components is more reasonable, reducing the generation and propagation of electromagnetic interference, thereby improving the electromagnetic compatibility of the cavity filter jumper. This helps to ensure that the cavity filter jumper can work normally in a complex environment, avoid interference with other electronic components or systems, and also improve its own anti-interference ability.

[0081] In a possible implementation, in the plurality of resonant assemblies 200 , the first plane 212 of the first portion first element 210 , the second plane 222 of the first portion second element 220 , and the first surface of the common resonant component 100 are arranged coplanarly.

[0082] And / or, the first plane 212 of the second portion first element 210, the second plane 222 of the second portion second element 220, and the second surface of the common resonator 100 are arranged coplanarly.

[0083] Thus, by realizing the above coplanar arrangement, the cavity filter jumper can form a more compact structure in space. The coplanar relationship between the common resonator 100 and the first element 210 and the second element 220 on a specific surface can more effectively utilize space and reduce space waste without increasing the overall thickness or width.

[0084] In addition, since the above coplanar layout makes the signal transmission path more direct and symmetrical, the attenuation and distortion of the signal during transmission can be effectively controlled. In the same plane, the signal transmission distance is shorter and the interference is relatively small, so it can maintain high signal strength and integrity. This helps to improve the signal transmission quality of the cavity filter jumper, ensure the accuracy and stability of the transmitted and received signals, and meet the requirements of wireless communication systems for high-quality signal transmission.

[0085] In a possible implementation, the shared resonator 100 includes a first shared portion 110 and a second shared portion 120 that are connected to each other.

[0086] The first common portion 110 connects the first portion of the first element 210 and the first portion of the second element 220 in the same layer.

[0087] The second common portion 120 connects the second portion of the first element 210 and the second portion of the second element 220 in the same layer.

[0088] In the above embodiment, in a specific implementation, the first common part 110 and the second common part 120 are symmetrically arranged hemispherical resonant cavities, and the hemispherical surface of the first common part 110 is arranged opposite to and connected to the hemispherical surface of the second common part 120, and the first common part 110 and the second common part 120 are jointly arranged to form a common cavity.

[0089] In a specific implementation, the first common part 110 connects the first part first element 210 and the first part second element 220 in the same layer through the second connection membrane 600. The second common part 120 connects the second part first element 210 and the second part second element 220 in the same layer through different second connection membranes 600. The second connection membrane 600 can be set to a semi-cylindrical shape. The semi-cylindrical second connection membrane 600 serves as a coupling notch for connecting the common resonator 100 with the first element 210 and the second element 220, which makes it easier to transmit energy and has less energy loss, so that the cavity filter jumper has better performance.

[0090] Through the above implementation, H and L are adjusted to appropriate sizes, and by adjusting the radius of the second connecting diaphragm 600, the cavity filter jumper is manufactured using stereolithography technology after simulation and optimization, and experiments show that the cavity filter jumper has good channel isolation and performance stability, is suitable for high-frequency band applications, and has the advantages of integration and lightweight.

[0091] In a possible implementation, the cavity filter jumper designed by the above implementation has a schematic coupling topology as shown in FIG. Figure 4 As shown, P1 and P1+ represent the first connection terminal 300 on the first element 210 in one of the resonant components 200, that is, the signal input terminal. P2 and P2+ represent the second connection terminal 400 on the second element 220 in the resonant component 200, that is, the signal output terminal, and the solid arrow indicates the signal transmission channel 1 in the resonant component 200. P3 and P3+ represent the first connection terminal 300 on the first element 210 in another resonant component 200, that is, another signal input terminal, P4 and P4+ represent the second connection terminal 400 on the second element 220 in the resonant component 200, that is, another signal output terminal, and the dotted arrow indicates the signal transmission channel 2 in the resonant component 200.

[0092] The orthogonal degenerate modes of signal transmission channel 1 and signal transmission channel 2 are as follows: Figure 5 As shown, Figure 5 The mode on the middle left is TM201 mode. Figure 5The mode on the right side of the middle is the TM102 mode. When P1 and P1+ are loaded with differential mode (DM) signals, the DM signals can be transmitted to P3 and P3+ through signal transmission channel 1. Similarly, when P2 and P2+ are loaded with DM signals, the DM signals can also be sent to P4 and P4+. For common mode (CM) excitation, the polarities of the electric fields will cancel each other out, so the TM201 and TM102 modes cannot be excited, thereby achieving good CM suppression. This realizes the function of the cavity filter jumper.

[0093] The first element 210 is integrally formed with the common resonant component 100, and / or the second element 220 is integrally formed with the common resonant component 100. In a specific implementation, the common resonant component 100 and the multiple groups of resonant components 200 are integrally formed, and the integral forming can be achieved by but not limited to 3D printing technology or casting technology. The above-mentioned setting method improves the structural integrity of the cavity filter jumper. The first element 210 (or the second element 220) and the common resonant component 100 form a continuous and complete structure, and compared with the traditional split structure, the internal stress distribution is more uniform and the structural strength is higher. This improvement in integrity helps the cavity filter jumper to better withstand the influence of the external environment, such as vibration, impact, etc., and reduce the risk of performance degradation or failure caused by relative movement or looseness between components.

[0094] The cavity filter jumper provided in the present application can be applied in at least one of the following devices or systems, for example: indoor wireless coverage system, satellite communication system, mobile communication system, radar system, medical equipment, industrial automation equipment, audio equipment, and automotive electronic system.

[0095] The implementation principle of a cavity filter jumper in an embodiment of the present application is as follows: the cavity filter jumper provided in the present application includes a common resonant component 100 and multiple groups of resonant components 200, the common resonant component 100 is provided with a common cavity; the resonant component 200 includes multiple first elements 210 and multiple second elements 220; the first element 210 is provided with a first cavity, the first cavity is connected to the common cavity, the first cavities of the multiple first elements 210 are connected to each other, and the first element 210 is provided with a first connecting end 300; the second element 220 is provided with a second cavity, the second cavity is connected to the common cavity, the second cavities of the multiple second elements 220 are connected to each other, and the second element 220 is provided with a second connecting end 400; in the same resonant component 200, the first cavity of the first element 210 can be connected to the second cavity of the second element 220 through the common cavity.

[0096] In this way, the first connection end 300 on each first element 210 of the cavity filter jumper can be used as a signal input end, and the second connection end 400 on each second element 220 can be used as a signal output end. In the same resonant component 200, since there are multiple signal input ends and signal output ends, the signal has a differential transmission effect during transmission, and the cross transmission of several channel signals and the isolation function between the transmission channels of different resonant components 200 are integrated in a relatively compact structure. Since the first cavity of each resonant component 200 is connected to the common cavity, and the cavity connection between different components can be achieved through the common cavity, this reasonable structural layout is conducive to optimizing the signal transmission path and reducing the loss and distortion of the signal during transmission. The common resonant element 100 and the mutually independent first cavity and second cavity play a shielding and isolation role to a certain extent, prevent the crosstalk of signals between different channels, improve the anti-interference ability of the cavity filter jumper, and further improve the overall performance of the cavity filter jumper.

[0097] The shared resonant component and interconnected cavity design in this solution avoid unnecessary repeated structures, further optimize the overall size, make it more adaptable to the development trend of miniaturization, and are conducive to the miniaturization and integration goals of cavity filter jumpers.
