摘要
A Doherty power amplifier apparatus and power amplification method are disclosed in the present invention. The apparatus includes a main power amplifier apparatus and an auxiliary power amplifier apparatus, and the main power amplifier apparatus is configured to adopt a High Voltage Heterojunction Bipolar Transistor (HVHBT) device to amplify signal power, and the auxiliary power amplifier apparatus is configured to adopt a High Electron Mobility Transistor (HEMT) device to amplify signal power. A power amplification efficiency of a whole Doherty power amplifier will be enhanced substantially according to the present invention.
