Abstract: Provided are a power amplification apparatus and a transmitter. The power amplification apparatus includes power amplification modules each including a voltage output unit and a power amplification unit; the voltage output unit outputs a first voltage signal (VIN_A) and a second voltage signal (VIN_B). The power amplification unit includes a selector (MUX), a radio frequency processing circuit, and a first switch transistor (M1), the radio frequency processing circuit processes a baseband signal to output a first radio frequency signal to a source of the first switch transistor (M1), and the selector (MUX) is configured to correspondingly strobe the first voltage signal (VIN_A) or the second voltage signal (VIN_B) according to an operating state of the first switch transistor (M1).
