Abstract

The invention discloses a dielectric filter applied to a 5G communication system, a manufacturing method of the dielectric filter and communication equipment. The dielectric filter comprises: a circuit board, wherein the circuit board comprises a board core body and metal foils arranged on two opposite main surfaces of the board core body, and the circuit board is processed into a preset filter shape; and an electromagnetic shielding layer, wherein the electromagnetic shielding layer is arranged on the side surface of the plate core body exposed by the metal foils on the two sides. The production efficiency can be improved, no mold is needed, the production period is shortened, the cost is reduced, and the machining precision is improved.

Description

technical field [0001] The present application relates to the technical field of communication equipment, and relates to a dielectric filter applied to a 5G communication system, a manufacturing method thereof, and communication equipment. Background technique [0002] With the rapid development of communication technology, especially the upcoming 5G communication era, more stringent technical requirements are put forward for the system architecture. While achieving high-efficiency and large-capacity communication, system modules must be highly integrated, miniaturized, Lightweight and low cost. For example, while 5G Massive MIMO technology realizes the further expansion of system channels from the current 8 or 16 channels to 32, 64 or even 128 channels, it requires that the overall system architecture size not be too large, and even a certain degree of miniaturization is required. Microwave filters are the core components of the system, and their performance parameters, si...
