濾波器，顧名思義，用來過濾電磁波信號，是基站射頻單元的核心器件；緸V波器，主要分為兩大類：金屬腔體濾波器：工藝成熟、成本偏高，是2G/3G/4G時代的主流，主要用于RRU上。陶瓷介質濾波器：重量輕、尺寸小、成本低，是5G時代的主流，主要用于AAU上。
陶瓷介質濾波器中的電磁波諧振發生在介質材料內部，且陶瓷介質比空氣的介電常數高，因此體積更小、重量更輕。此外，陶瓷介質濾波器還具有Q值高、選頻特性好、工作頻率穩定性好、插入損耗可以滿足基站技術要求、可靠性好、溫漂性能更好，可以承受高功率等優點，并且實現量產化后其成本更低。隨著新建 5G 基站數量的增加，金屬腔體濾波器比重將逐漸減少，陶瓷介質濾波器滲透可望加速。
