Structure for reducing dielectric loss based on 5G ceramic dielectric filter

Technical Field

Background

Filters play a great role in the field of communications, and are frequency-selective devices that pass certain frequency components of a signal and greatly attenuate other frequency components. Broadly speaking, any channel for information transmission may be considered a filter. From the beginning of the development of telecommunications, filters have played an important role in circuits, and have been continuously developed along with the development of communication technology. New communication systems require the development of a new technology capable of extracting and detecting signals in a specific frequency band, and the development of such a new technology further accelerates the research and development of filter technology.

In the field of modern communication technology, however, almost none of the branches is affected by digital filtering techniques. Source coding, channel coding, modulation, multiplexing, data compression, adaptive channel equalization, etc., are widely used, and especially in applications such as digital communication, network communication, image communication, etc., digital filters are far from being used, which is almost impossible. The traditional filter is generally realized by a metal coaxial cavity, and the electromagnetic waves with different frequencies oscillate in the coaxial cavity filter, so that the electromagnetic waves with the resonant frequency of the filter are reserved, and the electromagnetic waves with other frequencies are dissipated in the oscillation. In the 3G/4G era, the metal coaxial cavity has lower cost, and a mature process becomes the mainstream choice of the market.

In response to the situation that the interference of the wireless environment is increasingly complex, the ceramic dielectric resonant filter is rapidly developed. With the development of mobile communication networks, commercial wireless frequency bands become very dense, so that the problem that a common metal cavity filter cannot realize high-inhibition system compatibility is caused, and the problem can be solved by manufacturing the cavity filter by adopting a ceramic dielectric material.
