Abstract: In view of the high peak to average ratio of 5G communication bandwidth, the power back off range of the core component power amplifier is determined by analyzing the equipment requirements, so that the power back off efficiency of the power amplifier can be kept at a high level within the broadband working range, so as to adapt to the purpose of reducing power consumption of 5G communication equipment. According to the demand characteristics, a broadband high efficiency power amplifier is designed, and the simulation results show that the scheme is effective and practical. This technology can be vigorously promoted and applied in the development of 5G base station transmitter equipment.
