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

Claim (Index 1):
A power amplifier, comprising:\n an envelope modulator separately coupled to a drain electrode of a main power amplifier and a drain electrode of an auxiliary power amplifier and configured to:\n obtain an envelope voltage according to a received envelope signal; and \n output the envelope voltage separately to the drain electrode of the main power amplifier and the drain electrode of the auxiliary power amplifier, \n wherein the main power amplifier, when in an operating state, is configured to:\n set the envelope voltage received from the envelope modulator as an operating voltage; and \n amplify a signal input from a source electrode of the main power amplifier, and \n wherein the auxiliary power amplifier is coupled in parallel to the main power amplifier, and when in an operating state, configured to:\n set the envelope voltage received from the envelope modulator as an operating voltage; and \n amplify a signal input from a source electrode of the auxiliary power amplifier.
