| Abstract: | Efficiency and linearity are two important indicators of power amplifier, which affecting the whole system performance. An effective approach is implemented to improve efficiency through comparing various method based on the Doherty power amplifier technology which having simple structure. First the basic principle of Doherty power amplifier is introduced, and then efficiency and gain curve are obtained by microwave simulation software ADS for Freescale chip MRF6S21140H in the 2110 ~ 2170MHz band. Finally, ... |
