摘要: A power amplifier, a radio remote unit (RRU), and base station, where the amplifier includes an envelope controller, main auxiliary amplifier. The both set voltage output by modulator as operating voltages, because voltages of may be adjusted simultaneously, symmetry is improved, efficiency loss occurring probability low, thereby enhancing
