Modular AFU structure

Abstract

The invention provides a modular AFU structure comprising a holding pole and an antenna unit detachably mounted on the holding pole. The antenna unit comprises an antenna cover, an antenna filter module, a power dividing plate, a rack and a power supply transceiving module, wherein the rack and the power supply transceiving module are mounted on the holding pole. The antenna filter module is mounted on the power dividing plate; the antenna filter module is composed of a plurality of integrated plastic carriers which are distributed in an array. High-performance plastic is used as a carrier; oscillators, the power dividing plate, a reflecting plate and filters are integrally formed. An oscillator power dividing circuit, a reflecting surface and a filter cavity are processed by using LDS andan electroplating process, the assembly time is greatly saved, and the cost of materials is greatly reduced; in addition, the module is used as an assembly unit, and the filters are relatively uniformly fixed relative to the oscillator units, that is to say, the positions of the filters corresponding to each group of oscillators are fixed, so that the phase consistency of the AFU is greatly improved, and the design of a filter matching circuit is simplified.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a modularized AFU structure. Background technique [0002] As the core key technology of 5G, large-scale antenna technology plays a vital role in meeting the technical requirements of eMBB, uRLLC and mMTC (massive machine type communication) services. For example, for eMBB scenarios, its main technical indicators are spectral efficiency, peak rate, energy efficiency, user experience rate, etc. High-order MU-MIMO transmission can obtain extremely high spectral efficiency. The influence of interference and noise tends to disappear, and the transmission power required to achieve the same coverage and throughput will also be reduced, improving energy efficiency. [0003] As we all know, the main function of an antenna is to provide wireless coverage, that is, to realize wireless signal transmission between a wired communication network and a wireless terminal.

Problems solved by technology

In layman's terms, the antenna is responsible for sending and receiving electromagnetic wave signals, and the filter is responsible for filtering or suppressing useless electromagnetic wave frequency signals. Among them, the 5G antenna adopts MIMO technology, and its demand for antenna filters has greatly increased. Cost, performance and assembly also put forward higher requirements, posing great challenges to manufacturers
