Embodiment Construction

[0082] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0083] To facilitate understanding, some terms appearing in the embodiments of the present invention are first explained:

[0084] Outphasing power amplifier: Outphasing power amplifier includes two parallel power amplifiers and two Outphasing combiners. Its working principle is that two power amplifiers respectively amplify the two out-of-phase input signals received, and the outphasing combiner combines the two amplified input signals, thereby improving the efficiency of the power amplifier.

[0085] As a radio frequency signal transceiver device, a wireless base station is used to provide radio frequency signals to mobile terminals within its signal coverage. Such as figure 1 As shown, the wireless base station 10 usually includes a control su...

Description

Technical field [0001] The invention relates to the field of power amplifiers, in particular to a power amplifier, a power amplification method, a power amplification control device and a method. Background technique [0002] As a radio frequency signal transceiver device, the wireless base station is used to amplify the input signal through a power amplifier (English: Power Amplifier, PA for short), and the transmitter transmits the amplified input signal. The power amplifier is the most energy-consuming component in the wireless base station, and its efficiency directly affects the power consumption of the entire wireless base station. [0003] In order to reduce the power consumption of wireless base stations, existing wireless base stations usually use Doherty (English: Doherty) power amplifiers. [0004] The Doherty power amplifier includes: a main power amplifier and at least one peak power amplifier, and the main power amplifier and each peak power amplifier are connected in ...
