提出了一种毫米波3路线性Doherty辐射器，采用多天线耦合和天线上的电流缩放串联合成器，以提高峰值和回退效率。解决了5G通信中高峰均比导致的效率问题。
There is a growing interest in exploring antenna-electronic co-designs that leverage antennas (including their low-loss metal structures, design versatility, multi-feed driving capabilities) as a new design paradigm to radically advance mm-wave front-end performance. In particular, enhancing the peak/back-off transmitting efficiency is essential for future mm-wave wireless communications, such as 5G, which will predominantly use complex modulations with large peakto-average-power ratio (PAPR) and extra power back-off (PBO) for linearity and reliability. Consequently, mm-wave transmitters often operate at deep PBO (9 to 12dB) with poor average efficiency. Although mm-wave Doherty/Outphasing PAs have been widely explored, there is limited success in high-order active load modulation for deep-PBO efficiency enhancement with high PA linearity, mainly due to the complexity and prohibitive loss of on-chip passive networks.
