Abstract: In this paper,the RF front-end transmitting part and the back-end receiving part are connected to form a radio frequency transceiver system. A complete analog and digital communication system was designed in the RF section using ADS software. The time domain waveform,transceiver gain,eye diagram,sensitivity and linearity of the RF communication system are analyzed. The eye diagram is optimized. The similarities and differences between the RF section and the common frequency band of the communication system are discussed. At the same time,combined with the hardware test data,the simulation results are added to the actual teaching session,and the various influencing factors in the RF communication system are discussed. While improving the quality of experimental teaching,the specific requirements of the actual wireless environment for the communication quality of RF systems are explored.
