下一代5G和Beyond-5G无线系统刺激了各种规模的毫米波电子系统和天线阵列的研究、开发和部署的大幅增长。还可以预见，在未来的通信和传感系统中，具有高频谱效率的大动态范围调制信号将被普遍采用。功率放大器(PA)作为天线和收发电子设备之间的接口，通常控制整个无线系统的输出功率、能量效率和可靠性。然而，在毫米波载波频率上广泛使用高动态范围信号使得功率放大器的设计变得非常复杂，并且需要在能效和线性度以及其他功率放大器性能之间达到最终的平衡。在这篇综述文章中，我们将首先介绍由于高动态范围信号对毫米波功率放大器的系统级要求和设计挑战。我们将回顾用于毫米波功率放大器和功率器件的先进的有源负载调制架构。然后，我们将通过几个设计实例介绍毫米波功率放大器技术和创新的最新进展。将概述用于相控阵MIMO和高毫米波频率的毫米波功率放大器的特殊设计考虑。我们还将分享我们对未来技术趋势和创新机会的愿景。
The next-generation 5G and beyond-5G wireless systems have stimulated a substantial growth in research, development, and deployment of mm-Wave electronic systems and antenna arrays at various scales. It is also envisioned that large dynamic range modulation signals with high spectral efficiency will be ubiquitously employed in future communication and sensing systems. As the interface between the antennas and transceiver electronics, power amplifiers (PAs) typically govern the output power, energy efficiency, and reliability of the entire wireless systems. However, the wide use of high dynamic range signals at mm-Wave carrier frequencies substantially complicates the design of PAs and demands an ultimate balance of energy efficiency and linearity as well as other PA performances. In this review paper, we will first introduce the system-level requirements and design challenges on mm-Waves PAs due to high dynamic range signals. We will review advanced active load modulation architectures for mm-Wave PAs and power devices. We will then introduce recent advances in mm-Wave PA technologies and innovations with several design examples. Special design considerations on mm-Wave PAs for phased array MIMOs and high mm-Wave frequencies will be outlined. We will also share our vision on future technology trends and innovation opportunities.
