Description

technical field [0001] The invention relates to an integrated MIMO system base station multi-antenna and multiplexer module device in the field of wireless communication. Background technique [0002] RF filters are at the center of many design issues in radio technology and have become one of the hot topics of research in the field of wireless communications. With the development of wireless communication technology, especially the development and application of multiple-input multiple-output MIMO communication system, more modules of the radio frequency front-end tend to be miniaturized and integrated. Traditional radio frequency filters mainly include dielectric filters and surface acoustic filters. Although the dielectric filter has the advantages of low insertion loss and large power capacity, its disadvantage is that it is too large to achieve miniaturization. Compared with the dielectric filter, the surface acoustic filter can be made smaller, but it is limited by t...
