![](https://revistas.uptc.edu.co/public/journals/9/cover_issue_384_es_ES.jpg)
Abstract
This paper shows the general concept of the Doherty power amplifier, highlighting its superiority, in terms of average efficiency, regarding to single-stage power amplifiers. Furthermore, the posibility of including preamplification stages, in both branches of the Doherty power amplifier is presented, with the goal of increasing its gain.Keywords
power amplifier, doherty, wireless communication, high gain, efficiency.
