Abstract
A radio-frequency power output device includes a cooling plate, a temperature detection module, and a control module. The cooling plate is provided with a first circuit board and a second circuit board respectively on two opposite sides thereof, and the first circuit board and the second circuit board are provided with a first radio-frequency power amplification circuit and a second radio-frequency power amplification circuit, respectively. The temperature detection module is used to obtain the temperature of the first circuit board and the temperature of the second circuit board. The control module controls, based on the temperature of the first circuit board, the first radio-frequency power amplification circuit to output a radio-frequency power signal at a target temperature, and controls, based on the temperature of the second circuit board, the second radio-frequency power amplification circuit to output a radio-frequency power signal at the target temperature.
