摘要

5G对PA设计提出了严峻的挑战。首先，由于电池的寿命，输出功率和效率是最重要的。由于QAM调制和/或OFDM技术，线性输出功率和效率之间的权衡通常受到高PAPR的挑战。但由于带宽要求高，这种重要的权衡在5G中受到了更大的挑战。此外，向更高频率的转换，其中更多的未使用频谱可用，也给整个PA架构带来负担。

Doherty techniques for 5G RF and mm-wave power amplifiers

5G poses severe challenges to PA design. In the first place, output power and efficiency are of prime importance because of battery lifetime. The tradeoff between linear output power and efficiency is typically challenged by the high PAPR due to QAM modulation and/or OFDM techniques. But this important trade-off is challenged even more in 5G due to the high bandwidth requirements. Furthermore, the shift to higher frequencies, where more unused spectrum is available, also puts a burden on the overall PA architecture.
