APPARATUS AND METHOD FOR IMPROVING EFFICIENCY IN POWER AMPLIFIER |
摘要 |
An apparatus and method for enhancing the whole efficiency of power amplification in a supply modulated amplifier are provided. The power amplification apparatus includes a controller, a Doherty power amplifier, and a supply modulated amplifier. The controller selects a power amplifier among the Doherty power amplifier and the supply modulated amplifier. The Doherty power amplifier amplifies a power of a transmission signal when the Doherty power amplifier is selected by the controller. The supply modulated amplifier amplifies the power of the transmission signal using a supply voltage determined considering the amplitude of the transmission signal, when the supply modulated amplifier is selected by the controller. |
