Description

technical field [0001] The invention relates to the technical field of filters, in particular to a stripline structure for reducing power consumption, a low-pass filter, a communication device and a system. Background technique [0002] With the advent of the 5G communication era, the requirements for the weight and volume of base station equipment are getting smaller and smaller. Due to the advantages of miniaturization, low loss and good temperature characteristics, dielectric filters have become an inevitable option for base station equipment in the 5G era. Among them The application of ceramic waveguide filter is the most representative. In the practical application of ceramic waveguide filters, it must be used with a low-pass filter for far-end suppression to form a filter component. Therefore, the final performance of the filter component not only depends on the ceramic waveguide filter itself, but also It is closely related to the low-pass filter. [0003] The low-p...

Problems solved by technology

For the ceramic waveguide filter technology used in the 5G era, the traditional solution is to reduce the loss of the ceramic filter part, such as using low dielectric constant ceramic materials, using multi-mode technology, etc., but using low dielectric constant materials It will increase the volume and cannot meet customer requirements; the use of multi-mode technology is less cost-effective, and the mass production is not high; in contrast, the optimization of the low-pass filter part has been ignored, but the stripline low-pass filter Not without room for optimization

[0005] From the perspective of electronic system design, current density is a very important indicator. The performance of the circuit is closely related to the amount of current, and the current density is determined by the size of the conductor. The essence of the circuit layer in the stripline low-pass filter is It is a metal layer that forms a specific pattern (used to form a stripline resonator circuit). Its structural size is very small. In addition, it is used in the high-frequency frequency domain (microwave band). Due to the skin effect, the current conduction area It will be more confined near the surface, thus increasing the current density. If the current density is too high, power will be lost in the form of heat energy, which will have adverse consequences on the overall performance of the filter.
