Abstract

The embodiment of the invention provides a power amplification device, a beamforming system, a transmitter and a base station, and is characterized in that the power amplification device comprises a power amplifier, a power supply and a power supply modulator; the power supply is connected with the power amplifier through the power supply modulator; the power amplifier is used for amplifying a first signal; the power supply modulator is used for controlling the power supply to provide working voltage for the power amplifier according to an envelope signal corresponding to the first signal; thepower amplification device is also used for amplifying a second signal, wherein the first signal is generated according to a part, of which the amplitude belongs to a preset amplitude interval, in the target amplified signal, and the second signal is generated according to the part, not belonging to the amplitude interval, of the target amplified signal. According to the technical scheme providedby the invention, the average efficiency of the power amplifier can be improved.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a power amplification device, a beam forming system, a transmitter and a base station. Background technique [0002] With the rapid growth of communication data transmission, the problem of power amplifier (power amplifier, PA) efficiency reduction is becoming more and more serious. The low efficiency not only increases the energy consumption of the transmitter, but also brings about the large size of the base station due to the high heat generation. A series of problems such as increased heat dissipation design cost and reduced reliability performance. Therefore, high-efficiency power amplifier technology has become the focus of current power amplifier design. [0003] The power amplifier used in the traditional beamforming system is a class AB power amplifier. The maximum amplitude of the amplified signal that this type of power amplifier can support is determ...
