A ceramic filter for 5g communication

Abstract

The invention belongs to the technical field of filters, and specifically relates to a ceramic filter for 5G communication. The ceramic filter comprises a substrate and a plurality of pins leading outfrom the inside of the substrate; two half-shells are fixedly connected to the outer side of the substrate, and the half-shells are hollow; a first connecting plate and a second connecting plate arerespectively fixedly connected to the bottoms of the two half-shells; the middle parts of the first connecting plate and the second connecting plate penetrate through a same fixed shaft respectively;a connecting rod is fixedly connected to the top of the fixed shaft; and the top end of the connecting rod is adhered with the substrate. According to the ceramic filter for the 5G communication provided by the invention, the half-shells are arranged, the characteristic of expansion caused by heat and contraction caused by cold of mercury inside an outer tube is used, and a guide rod is driven tomove when an elastic rod is restored, so that the first connecting plate and the second connecting plate rotate on the fixed shaft, therefore, the two half-shells are in contact or opened states, andduring working at night, a heat preservation effect is achieved; and meanwhile, heat generated inside the substrate is wrapped inside the two half-shells, so that the influence of low temperature is reduced, and the stability of the working process is ensured.

Description

technical field [0001] The invention belongs to the technical field of filters, in particular to a ceramic filter for 5G communication. Background technique [0002] The ceramic filter is made of lead zirconate titanate ceramic material. The ceramic material is made into a sheet, and silver is coated on both sides as an electrode. After DC high-voltage polarization, it has a piezoelectric effect. With the continuous development of modern communication technology With the development, the requirements for filters are getting higher and higher. The filter technology of small size, high performance, high power and low cost is particularly important for filters in wireless communication applications. The ceramic filter required inside the 5G array antenna device, its performance in all aspects has strict requirements. [0003] In order to seize the 5G communication market, 5G base stations will be deployed in some areas with harsh environments before other manufacturers enter. ...

Problems solved by technology

[0003] In order to seize the 5G communication market, 5G base stations will be deployed in some areas with harsh environments before other manufacturers enter. Ceramic filters need to be used in 5G base stations. When the existing ceramic filters are used in plateau areas, due to their use The particularity of the environment - the temperature difference between day and night is large. When used at night, the temperature will be particularly low, which will affect the work of the ceramic filter. In view of this, the present invention provides a ceramic filter for 5G communication, which can reduce the special environment in plateau areas. The impact on the low ceramic filter ensures the stability when working
