Description

Technical Field

[0001] This application relates to wireless communication technology, and more particularly to a cavity filter jumper. Background Technology

[0002] Filters are crucial components in radio frequency (RF) circuits, primarily functioning to select and filter transmit and receive frequency signals, eliminating unwanted frequencies to ensure accurate transmission and reception. Cavity filter jumpers, a type of passive device commonly used in microwave circuits, enable cross-transmission of signals from multiple channels while maintaining isolation between them. With the rapid development of wireless communication technology in industrial and consumer electronics sectors, higher demands are being placed on cavity filter jumpers, requiring miniaturization and integration.

[0003] However, existing cavity filter jumpers are large in size, have high losses, and low quality factors, which are not conducive to miniaturization and integration. Summary of the Invention

[0018] In one possible implementation, the cavity filter jumper provided in this application includes a first coaxial probe and a first coaxial power connector at the first connection end, wherein the first coaxial power connector is connected to the first coaxial probe, and a portion of the first coaxial probe is inserted into the corresponding first element.

[0019] And / or, the second connection end includes a second coaxial probe and a second coaxial power connector, the second coaxial power connector being connected to the second coaxial probe, and a portion of the second coaxial probe being inserted into the corresponding second element.

[0026] The cavity filter jumper provided in this application includes a common resonator and multiple sets of resonant components. The common resonator is provided with a common cavity.

[0047] Wireless communication technology is rapidly developing in industrial and consumer electronics sectors, creating a high demand for various high-performance microwave devices. In modern wireless communication systems and indoor distributed antenna systems (DAS), balanced circuits are widely used due to their high immunity to environmental noise and electromagnetic interference. Balanced bandpass filters, in particular, have received considerable research attention. Meanwhile, jumpers are already widely used in multi-channel systems. To achieve size reduction and simplified circuit design, cavity filter jumpers, as functionally 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 implementations. However, existing devices struggle to meet the demands of indoor applications requiring low loss, high power handling capabilities, and a high on-premises quality factor.

[0048] Cavity filter jumpers based on traditional transmission structures typically 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-mentioned technical problems, this application provides a cavity filter jumper. In this technical solution, the cavity filter jumper provided by this application includes a common resonator and multiple sets of resonant components. The common resonator is provided with a common cavity. The resonant components include multiple first elements and multiple second elements. The first element is provided with a first cavity, which is connected to the common cavity. The first cavities of the multiple first elements are interconnected, and the first element is provided with a first connection terminal. The second element is provided with a second cavity, which is connected to the common cavity. The second cavities of the multiple second elements are interconnected, and the second element is provided with a second connection terminal. 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 this configuration, the first connection terminals on each first element of the cavity filter jumper can serve as signal input terminals, and the second connection terminals on each second element can serve as signal output terminals. Because multiple signal input and output terminals are provided within the same resonant assembly, differential transmission is achieved during signal transmission. This integrates the cross-transmission of signals from several channels and the isolation function between transmission channels of different resonant assemblies into a relatively compact structure. Since the first cavities of each resonant assembly are connected to a shared cavity, and the shared cavity enables cavity communication between different elements, this rational structural layout optimizes the signal transmission path and reduces signal loss and distortion during transmission. The shared resonant element and the independent first and second cavities provide shielding and isolation to a certain extent, preventing crosstalk between different channels, improving the anti-interference capability of the cavity filter jumper, and further enhancing its overall performance.

[0051] The shared resonator and interconnected cavity design in this scheme avoid unnecessary repetitive structures, further optimize the overall size, and make it more suitable for the trend of miniaturization, which is conducive to the miniaturization and integration of cavity filter jumpers.

[0052] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0053] Reference Figure 1 , Figure 2 and Figure 3 As shown in the figure, a cavity filter jumper provided in this application embodiment includes a common resonator 100 and multiple sets of resonant components 200, and the common resonator 100 is provided with a common cavity.

[0054] The resonant assembly 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 interconnected, and the first element 210 is provided with a first connection end 300.

[0055] The second element 220 is provided with a second cavity, which is connected to a common cavity. The second cavities of multiple second elements 220 are interconnected. The second element 220 is provided with a second connection end 400.

[0056] In the same resonant assembly 200, the first cavity of the first element 210 can be connected to the second cavity of the second element 220 through a shared cavity.

[0057] In the above embodiments, by setting a structure with a shared resonator 100 and multiple sets of resonant components 200, more functional components can be integrated within a limited space compared to traditional structural designs. The shared cavity design allows the resonant components 200 to be arranged around it, reducing the overall space occupied and facilitating the miniaturization of the cavity filter jumper, thus meeting the miniaturization requirements of wireless communication technology in industrial and consumer electronics sectors. The shared resonator 100 and interconnected cavity design in this scheme avoid unnecessary structural duplication, further optimizing the overall size and making it more adaptable to the trend of miniaturization.

[0058] With this configuration, the first connection terminal 300 on each first element 210 of the cavity filter jumper can serve as a signal input terminal, and the second connection terminal 400 on each second element 220 can serve as a signal output terminal. Since multiple signal input and output terminals are provided within the same resonant component 200, differential transmission is achieved during signal transmission. This integrates the cross-transmission of signals from several channels and the isolation function between the transmission channels of different resonant components 200 into a relatively compact structure. Because the first cavity of each resonant component 200 is connected to a shared cavity, and cavity communication between different components can be achieved through the shared cavity, this reasonable structural layout helps optimize the signal transmission path and reduce signal loss and distortion during transmission. The shared resonant component 100 and the independent first and second cavities provide shielding and isolation to a certain extent, preventing crosstalk between different channels, improving the anti-interference capability of the cavity filter jumper, and further enhancing the overall performance of the cavity filter jumper.

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

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

[0061] In the same resonant component 200, there are two second elements 220.

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

[0063] In the above embodiments, to achieve the goals of miniaturization and integration, waveguide cavity devices have been widely studied due to their advantages of low insertion loss and high quality factor (Qu) in high-frequency bands. However, the research and design of cavity filter jumpers based on waveguide structures are insufficient. Compared with rectangular and cylindrical metal waveguide resonant cavities, spherical resonant cavities have higher Qu values. Hemispherical resonant cavities inherit the advantages of spherical resonant cavities, possessing many degeneracy modes, which can be used to design balanced cavity filter jumpers. Furthermore, hemispherical cavities reduce the volume by half compared to spherical cavities, making further miniaturization easier. By designing the first element 210 as having a first hemispherical surface 211 and a first plane 212 with the first hemispherical surfaces 211 of the two first elements 210 close to each other, and designing the second element 220 as having a second hemispherical surface 221 and a second plane 222 with the second hemispherical surfaces 221 of the two second elements 220 close to each other, the elements can be arranged more rationally within a limited space.

[0064] This design, which places the first element 210 and the second element 220 in a hemispherical shape, achieves a compact layout, significantly reduces unnecessary spacing and gaps, and thus effectively reduces the overall space occupied by the cavity filter jumper. This helps to achieve device miniaturization and meets the miniaturization requirements of wireless communication technology in the industrial and consumer electronics sectors.

[0065] The structure of the first hemisphere 211 of the first element 210 and the second hemisphere 221 of the second element 220 being close to each other makes the signal distribution inside the resonant assembly 200 more uniform and stable. This helps to improve the electromagnetic characteristics of the cavity filter jumper, such as reducing losses and improving selectivity, thereby improving the performance of the cavity filter jumper and better meeting the requirements of wireless communication systems for high-performance microwave devices. The performance indicators of the cavity filter jumper, such as resonant frequency, bandwidth, and isolation, can be precisely controlled by adjusting parameters such as the hemispherical radius, planar dimensions, and relative positions of the first element 210 and the second element 220, so as to better meet the specific needs of different application scenarios and further expand the application range and performance advantages of the cavity filter jumper.

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

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

[0069] Furthermore, this arrangement makes the signal transmission path inside the resonant component 200 clearer and simpler. The first planes 212 of the two first elements 210 are far apart and parallel to each other, and the second planes 222 of the two second elements 220 are far apart and parallel to each other, which facilitates circuit wiring and connection within the same layer, reduces the complexity of cross-layer connections, thereby enhancing the circuit integration of the cavity filter jumper and better adapting to the development trend of highly integrated modern electronic devices.

[0070] In one possible implementation, the two first elements 210 and the two second elements 220 in the same resonant assembly 200 are connected by different first connecting diaphragms 500. Specifically, the first connecting diaphragm 500 can be configured as a cylinder, which makes it easier to transmit energy and reduces energy loss, thus making the cavity filter jumper perform better.

[0071] In one possible implementation, the first connection end 300 is located on the first hemisphere 211, and in the same resonant component 200, the first connection end 300 is located between two first planes 212.

[0072] And / or, the second connection end 400 is located on the second hemisphere 221, and in the same resonant component 200, the second connection 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 hemisphere 211 and the second hemisphere 221, and are located between the corresponding two first planes 212 and two second planes 222, making the spatial distribution of each first element 210 and the second element 220 within the resonant assembly 200 more orderly and compact. This reduces the spatial footprint of the entire cavity filter jumper, contributing to the miniaturization of the device.

[0074] In one possible implementation, in the same resonant component 200, the connection between the first connection terminal 300 and the second connection terminal 400 passes through a common resonant component 100.

[0075] In the above embodiments, by having the connection between the first connection terminal 300 and the second connection terminal 400 pass through the common resonator 100, the space required for additional connection paths is reduced, making the entire cavity filter jumper more structurally streamlined. This helps to reduce its overall size and achieve more functional integration within a limited space. The precise positions of the first connection terminal 300 and the second connection terminal 400 help to shorten the signal transmission path and reduce adverse effects such as reflection and scattering of the signal during transmission. This allows the signal to be transmitted more quickly and accurately in the resonator 200, thereby improving the signal transmission quality of the cavity filter jumper.

[0076] In the specific implementation, 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 power connector 320. The first coaxial power 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 power connector 420. The second coaxial power 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 assembly 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 assembly 200 are parallel and coplanar.

[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. 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 size of H and L, the coupling between the first connection end 300 and the first element 210 and the second connection end 400 and the second element 220 can be controlled. Adjusting H and L to a suitable size can achieve good return loss, thereby reducing the overall loss of the cavity filter jumper.

[0079] In one possible implementation, in the same resonant assembly 200, the first portion of the first element 210 and the first portion of the second element 220 are arranged in the same layer, and the second portion of the first element 210 and the second portion of the second element 220 are arranged in the same layer.

[0080] In the above embodiments, this layered, co-layered arrangement fully utilizes the space of the cavity filter jumper. By rationally arranging the first element 210 and the second element 220 in the vertical direction, wasted space is avoided, and the dimensions of the cavity filter jumper in all directions are more balanced and compact. This allows the entire cavity filter jumper to accommodate more functional components in a smaller space, contributing to the miniaturization of the device. Furthermore, this arrangement results in more uniform and stable signal transmission within the cavity filter jumper. With the first part of the first element 210 and the first part of the second element 220 arranged in the same layer, and the second part of the first element 210 and the second part of the second element 220 arranged in the same layer, the electromagnetic coupling between the components is more rational, reducing the generation and propagation of electromagnetic interference, thereby improving the electromagnetic compatibility of the cavity filter jumper. This helps ensure that the cavity filter jumper can operate normally in complex environments, avoiding interference to other electronic components or systems, and also improving its own anti-interference capability.

[0081] In one possible implementation, among the plurality of resonant components 200, the first plane 212 of the first portion of the first element 210, the second plane 222 of the first portion of the second element 220, and the first surface of the common resonator 100 are arranged coplanarly.

[0082] And / or, the first plane 212 of the second part first element 210, the second plane 222 of the second part second element 220, and the second surface of the common resonator 100 are arranged in a coplanar manner.

[0083] In this way, by achieving the above-mentioned coplanar arrangement, the cavity filter jumper can form a more compact structure in space. The coplanar relationship between the shared resonator 100 and the first element 210 and the second element 220 on a specific surface can make more efficient use of space and reduce space waste without increasing the overall thickness or width.

[0084] Furthermore, the coplanar layout described above makes the signal transmission path more direct and symmetrical, effectively controlling signal attenuation and distortion during transmission. Within the same plane, the signal transmission distance is shorter and subject to relatively less interference, thus maintaining higher signal strength and integrity. This helps improve the signal transmission quality of the cavity filter jumper, ensuring the accuracy and stability of transmitted and received signals, and meeting the requirements of wireless communication systems for high-quality signal transmission.

[0085] In one possible implementation, the common resonator 100 includes a first common portion 110 and a second common portion 120 that are connected.

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

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

[0088] In the above embodiment, specifically, 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 and the hemispherical surface of the second common part 120 are arranged opposite to each other and connected, and the first common part 110 and the second common part 120 together form a common cavity.

[0089] In a specific implementation, the first common part 110 connects the first element 210 and the second element 220 of the same layer via a second connecting diaphragm 600. The second common part 120 connects the second element 210 and the second element 220 of the same layer via different second connecting diaphragms 600. The second connecting diaphragm 600 can be configured as a semi-cylindrical shape. The semi-cylindrical second connecting diaphragm 600 serves as a coupling notch for connecting the common resonator 100 with the first element 210 and the second element 220, making it easier to transmit energy and reducing energy loss, thus improving the performance of the cavity filter jumper.

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

[0091] In one possible implementation, the cavity filter jumper designed according to the above embodiments has the following schematic coupling topology: Figure 4 As shown, P1 and P1+ represent the first connection terminal 300 on the first element 210 of one of the resonant components 200, which is the signal input terminal. P2 and P2+ represent the second connection terminal 400 on the second element 220 of the resonant component 200, which is the signal output terminal. The solid arrow indicates the first signal transmission channel in this resonant component 200. P3 and P3+ represent the first connection terminal 300 on the first element 210 of another resonant component 200, which is another signal input terminal. P4 and P4+ represent the second connection terminal 400 on the second element 220 of the resonant component 200, which is another signal output terminal. The dashed arrow indicates the second signal transmission channel in this resonant component 200.

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

[0093] The first element 210 is integrally formed with the common resonator 100, and / or the second element 220 is integrally formed with the common resonator 100. In specific implementations, the common resonator 100 and multiple sets of resonant components 200 are integrally formed, which can be achieved through, but is not limited to, 3D printing or casting technology. This arrangement improves the overall structural integrity of the cavity filter jumper. The first element 210 (or the second element 220) and the common resonator 100 form a continuous and complete structure, which, compared to the traditional split structure, has a more uniform internal stress distribution and higher structural strength. This improved integrity helps the cavity filter jumper better withstand the influence of the external environment, such as vibration and impact, reducing the risk of performance degradation or failure due to relative movement or loosening between components.

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

[0095] The implementation principle of a cavity filter jumper according to an embodiment of this application is as follows: The cavity filter jumper provided in this application includes a common resonator 100 and multiple sets of resonant components 200. The common resonator 100 is provided with a common cavity. The resonant components 200 include multiple first elements 210 and multiple second elements 220. The first element 210 is provided with a first cavity, which is connected to the common cavity. The first cavities of the multiple first elements 210 are interconnected. The first element 210 is provided with a first connection end 300. The second element 220 is provided with a second cavity, which is connected to the common cavity. The second cavities of the multiple second elements 220 are interconnected. The second element 220 is provided with a second connection 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] With this configuration, the first connection terminal 300 on each first element 210 of the cavity filter jumper can serve as a signal input terminal, and the second connection terminal 400 on each second element 220 can serve as a signal output terminal. Since multiple signal input and output terminals are provided within the same resonant component 200, differential transmission is achieved during signal transmission. This integrates the cross-transmission of signals from several channels and the isolation function between the transmission channels of different resonant components 200 into a relatively compact structure. Because the first cavity of each resonant component 200 is connected to a shared cavity, and cavity communication between different components can be achieved through the shared cavity, this reasonable structural layout helps optimize the signal transmission path and reduce signal loss and distortion during transmission. The shared resonant component 100 and the independent first and second cavities provide shielding and isolation to a certain extent, preventing crosstalk between different channels, improving the anti-interference capability of the cavity filter jumper, and further enhancing the overall performance of the cavity filter jumper.

[0097] The shared resonator and interconnected cavity design in this scheme avoid unnecessary repetitive structures, further optimize the overall size, and make it more suitable for the trend of miniaturization, which is conducive to the miniaturization and integration of cavity filter jumpers.
