Abstract:At present,5G communication technology has been widely used in mobile communication,human-computer interaction and video transmission. With the rapid development of 5G communication technology,the overall performance requirements of hardware devices are also gradually improved. Filter plays an indispensable role in 5G based communication technology,which is usually used to suppress the interference of communication signal. Therefore,the filter with high performance and small size has become a key study issue in the field of components. Based on the introduction of LTCC technology and the prototype of low-pass filter,this paper proposes the design scheme of filter circuit model,which can meet the high performance requirements of 5G communication components.
