Unformatted text preview: response of a power amplifier. Operation in the linear region of this response is generally required to avoid signal distortion, so the peak value is constrained to be in this region. Clearly it would be desirable to have the average and peak values be as close together as possible in order to have the power amplifier operate at the maximum efficiency. Additionally, a high PAPR requires high resolution for the receiver ADC, since the dynamic range of the signal is much larger for high PAPR signals. High resolution ADCs place a complexity and power burden on the receiver front end. Figure 3_1. Typical Response of a Power Amplifier ...
