With the rapid development of 5G technology,massive multiple-input multiple-output(Massive MIMO)technol-ogy has become one of the key technologies of 5G.This technology contains multiple radio frequency(RF)channels.The number of filters in the system increases significantly,making 5G filters have higher requirements for miniaturization and high integration while maintaining high performance.This paper first introduces the basic requirements of 5G RF base sta-tion filters,and then focuses on the form and characteristics of RF base station filter,including microstrip,waveguide cavi-ty,coaxial,dielectric loaded,and ceramic dielectric filters.Through an examination of the features and current research trends of these different filter types,coupled with a comprehensive comparison,it becomes evident that ceramic dielectric filters offer substantial potential for development in 5G base stations,particularly in terms of performance,size,and cost.
