Abstract： Aiming at the development requirements of 5G small base station project, based on the theoretical research of 5G communication system and the requirements of 3GPP RF performance indicators, a 3.5 GHz RF front-end is designed and developed by Advanced Design System（ADS）simulation software. According to the whole development process of RF front-end, this paper conducts in-depth research and evaluation on the performance parameters of key RF components such as power amplifier, low noise amplifier, RF switch and filter, and puts forward the corresponding schematic design, system link simulation and optimization of board and end test indicators. Finally, the actual test of board and end performance indicators is passed. All the index data meet the technical requirements.
