To deal with the efficiency and linearity of PA in base station, the Doherty amplifier structure is adopted in this paper, and we solve this problem successfully via load-pull design technique in ADS platform. A balanced amplifier and a Doherty amplifier have been designed. They are applied in the frequency range of 1930–1990MHz for base stations. We make a comparison of the power added efficiency...
In order to solve the conflict between the efficiency and the linearity of a power amplifier in the base station, the Doherty structure is adopted to design the power amplifier in this paper. The problem is successfully solved in Agilent's ADS design platform by incorporating with the load-pull technology. A single amplifier, a balanced amplifier and a Doherty amplifier are designed in this work,...
