  • High-Efficiency Power Amplifier
    Publication number: 20100253426
    Abstract: A high-efficiency power amplifier is provided, including a drive amplifier and a final power amplifier, and further including a first digital pre-distortion (DPD) correction module and a second DPD correction module. The first DPD correction module is configured to pre-distort nonlinear characteristics of drive signals output by the drive amplifier, and the second DPD correction module is connected to the first DPD correction module in series, and is configured to pre-distort nonlinear characteristics of amplified signals output by the final power amplifier. Another high-efficiency power amplifier is also provided, including a drive amplifier and a final power amplifier, and further including a second multi-path control module, a fourth DPD correction module, and a second gating module. The overall efficiency of the high-efficiency power amplifier is increased by improving the working efficiency of the drive amplifier.

  • METHOD AND DEVICE FOR CONTROLLING POWER AMPLIFICATION
    Publication number: 20100112966
    Abstract: A method and an NE for controlling power amplification are provided. The method for controlling power amplification includes: outputting a voltage signal according to the state of an NE; applying the voltage signal to a grid electrode or a base electrode of at least one power amplifier transistor in a power amplifier. Thus, static power dissipation of the power amplifier can be eliminated when no RF power is output, and the efficiency of the power amplifier can be improved by using the above method and NE.
