| Popis: | The design of a 10 W symmetrical Doherty power amplifier in the 900 MHz band is being presented. A short analysis of the Doherty's technique is discussed and the design procedure is described. In order to achieve proper load modulation for maximum efficiency during the 6-dB back-off region an uneven Wilkinson power divider was implemented. The designed Doherty power amplifier was then simulated and realized to validate the expected performance and functionality. |
