Abstract

The power amplifier (PA) is usually the primary consumer of DC power in most hand-held wireless devices, so amplifier efficiency is a very important consideration. To solve this problem, we need to design high-efficiency PA for LTE (Long Term Evolution) that reduce noise when transmit the signal. In communication, basically they use Class A & AB power amplifier. It is because it has higher gain with reduced spectral content but its efficiency below than 70%. The expected efficiency power amplifier for this project is more than 70%. The power-modulation process must be efficient, since only the delivered power (sometimes only part of it) is to be interpreted by the receiver. Efficient power amplifiers are necessary in state-of-the-art technology and are going to be necessary in the future as well. The main objective for this project is to design and develop high-efficiency power amplifier for LTE. In order to achieve the objective, several methodologies have been proposed. In the beginning, literature review including understanding of power amplifier parameters and structure will be studies. Later on, we will design and analyze the power amplifier. At the end of the project, I will learn about power amplifier design and technique. Parameter that will use in this project is return loss. We use Microwave measurement technique to calculate the measurement for this design. In this project, I already finished design power amplifier for LTE.
