A power amplifier tube and a power amplification method are disclosed in the present invention. The power amplifier tube includes a high voltage heterojunction bipolar transistor (HVHBT) power amplifier tube core and a high electron mobility transistor (HEMT) power amplifier tube core, and the HVHBT power amplifier tube core and the HEMT power amplifier tube core are integrated in the same encapsulation. In the present invention, it should be configured as a Doherty amplifier, and the power tube is designed in a breakthrough combination manner of new power amplifier tube cores, compared with all the existing Doherty amplifiers which employ LDMOS power amplifier tube cores, the power amplification with high efficiency can be achieved on the basis of ensuring small volume of power amplifier tube.
