Abstract
Embodiments of the disclosure relate to optimizing power efficiency of a power amplifier circuit to reduce power consumption in a remote unit in a wireless distribution system (WDS). A power amplifier circuit is provided in the remote unit to amplify a received input signal associated with a signal channel(s) to generate an output signal at an aggregated peak power. In this regard, a control circuit is configured to analyze at least one physical property related to the signal channel(s) to determine a maximum output power of the power amplifier circuit. Accordingly, the control circuit configures the power amplifier circuit according to the determined maximum output power. By configuring the maximum output power based on the signal channel(s) in the input signal, it may be possible to optimize the power efficiency of the power amplifier circuit, thus helping to reduce the power consumption of the remote unit.
