Description

Technical Field

[0001] The present invention relates to the technical field of filters, and in particular to a topological structure, a band-stop filter and communication equipment. Background Art

[0002] With the development of modern communication technology, people's demand for information transmission is gradually increasing. However, spectrum resources are relatively limited. Various communication systems and communication modes are getting closer and closer to each other or even interlaced in frequency space. This requires each communication system to have better anti-interference ability to prevent interference from other systems. In addition, with the increasing density of electronic devices, future communication systems will develop in the direction of miniaturization. As a result, the miniaturization and high selectivity of filters have gradually become a research hotspot in communication technology.

[0003] At present, the selectivity of the band-stop filter is mostly improved by setting a plurality of open branches on the topological structure within the band-stop filter, such as a topological structure, a band-stop filter and a communication device disclosed in Chinese Patent Publication No. CN220963707U. However, since the number of open branches on the topological structure is fixed, it cannot be adjusted according to different practical needs, which results in a small application range of the topological structure.

[0004] When the number of open branches in a topology is fixed and cannot be adjusted according to practical needs, it will bring a series of impacts and limitations, especially in the fields of engineering design, communications, electronic circuits, network layout, etc.:

[0005] 1. Limited design flexibility: The fixed number of open branches makes it impossible for designers to optimize the topology according to specific application requirements. In some cases, more open branches may be required to achieve specific performance requirements, or some branches may be reduced to reduce costs or improve efficiency. However, due to the fixed number, these optimization strategies may not be implemented.

[0006] 2. Limited performance: The performance of a topology often depends on the configuration of its open branches. When the number of open branches is fixed, the topology may not achieve optimal performance in all applications. For example, in a communication network, a fixed number of open branches may limit the transmission quality and bandwidth of the signal.

[0007] 3. Increased costs: Due to limited design flexibility, it may be necessary to compensate for the shortcomings of the topology itself through other means (such as adding additional hardware devices or software functions). This will lead to additional cost investment and may reduce the cost-effectiveness of the entire system.

[0008] 4. Limited scalability: As technology advances and application requirements grow, it may be necessary to expand the topology to a larger scale or more complex configuration. However, when the number of open branches is fixed, such expansion may become difficult or impossible. This will limit the scope of application and adaptability of the topology in future developments.

[0009] 5. Difficulty in maintenance: Since fixed topology is difficult to adapt to changing needs, it may encounter more difficulties during maintenance and upgrades. For example, when the system fails or needs to be upgraded, it may be necessary to replace the entire topology instead of simply modifying or replacing some components.

[0010] 6. Reduced customization capabilities: In some cases, customers may require customized topologies to meet their specific needs. However, when the number of open branches is fixed, the ability to provide customized solutions will be limited. This may lead to reduced customer satisfaction or loss of market share.
