Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a radio frequency power amplifier applied to 5G millimeter wave mobile communication. Background technique [0002] With the rapid development of the information age, people have put forward higher requirements for wireless communication capacity. With the advantages of high frequency band and large capacity, microwave communication technology has developed rapidly in recent decades. The IMT-2020 promotion group defines the high-frequency spectrum as 6-100GHz, and above 30GHz belongs to the millimeter wave spectrum. With the continuous development of microwave systems, miniaturization, high reliability, and strong anti-interference ability are the future development trends. The wavelength of millimeter wave is shorter than that of microwave. It has the characteristics of small antenna size, high resolution, strong directionality, large amount of information, high me...
