[0002] In network communication systems, a network filter is an electronic component or device used to process signal transmission and suppress interference. Its core function is to "allow signals of specific frequencies to pass through while blocking or attenuating unwanted frequency components," ensuring stable and efficient transmission of network signals. It is widely used in various wired / wireless network scenarios such as Ethernet, WiFi, 5G / 4G, and fiber optic communication, and is one of the key components for ensuring communication quality.

[0003] With the trend of increasing transmission speed in electronic products, network filters, as an important component for the transmission of weak electrical signals in electronic products, are increasingly being demanded by the industry towards multi-channel, high-speed, and miniaturized designs.

[0004] Currently, conventional network filters function to transmit network signals. These signals are optimized by the network filters after passing through the motherboard before being transmitted. When a motherboard uses multiple network filters, the common practice is to directly arrange the individual network filters in an array on the motherboard. This method occupies too much motherboard space, severely hindering the miniaturization and high-speed development of products. Therefore, it is necessary to research a solution to address these issues. Utility Model Content
