Advantages and Disadvantages of LNA and PA in Wireless Communication

Wireless communication technology has a wide range of applications in all walks of life Wireless communication makes the acquisition, transmission and sharing of information more convenient and rapid, and helps to promote the popularization and progress of education, medical care, public services and other fields. For example, telemedicine can provide timely diagnosis and treatment to people in remote areas through wireless communication technology. Moreover, with the development and popularization of wireless communication technology, more and more third world countries have begun to build more wireless communication base stations to improve people’s living quality. This paper will first introduce the application and design of low noise amplifier. Then the applications of high-power amplifiers are discussed, with emphasis on the design and optimization of multistage Doherty amplifiers. The two amplifiers will be compared and analyzed to summarize their application advantages and limitations in wireless communication and analyze their applicability and potential improvement directions in different communication environments. Finally, the research content of this paper will be summarized, and the direction of future research will be proposed.
