摘要： The present invention discloses a remote radio unit and a base station system. The remote radio unit includes an active part and a passive part, where the active part and the passive part are placed respectively on an active module and a passive module that are independent of each other and the active module and the passive module are connected via a pluggable connecting device. Because the passive part is more reliable and less liable to breakdown than the active part, when the active part needs to be repaired, it is unnecessary to dismantle the entire unit. Therefore, the repair is easier and faster and the repair cost is lower. The operation reliability of the base station system is also improved.

摘要： 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. Further, higher overall efficiency is also achieved for a power amplifier with a higher gain.
