Abstract

The invention discloses a preparation method of a polymer material filter, which comprises the following steps of: 1, manufacturing a filter substrate by using thermoplastic plastics in an injection molding or compression molding manner; 2, performing surface coating treatment on the filter substrate to enable the surface of the filter substrate to be covered with a metal coating to form the filter. The manufacturing process is simple, the forming period is short, the production efficiency is high, automatic operation is easy to achieve, the machining adaptability is high, the size between batches is stable, and the product weight is light.

Description

technical field [0001] The invention relates to the technical field of filter preparation, in particular to a method for preparing a polymer material filter. Background technique [0002] With the substantial increase in the number of 5G antenna channels and the integration of antennas and RRUs into AAUs, the size of the filter has been greatly reduced in the new 5G macro base station, but there will be more than 30 filters in the macro base station. Existing filters are generally made of aluminum alloy, ceramics and other materials, which are not only heavy, not conducive to installation, disassembly and transportation, but also due to the high processing cost of metal or ceramics, the processing procedures are cumbersome, the cycle is long, and it is difficult to realize complex structures. Requirements lead to high cost of filters and it is difficult to meet the needs of 5G base stations for large filter structures and usage, which severely limits the development of filte...
