该论文提出了一种24-30GHz瓦级宽带线性Doherty功率放大器，采用多初级分布式有源变压器功率合成技术，解决了5G毫米波用户设备中因天线阵列数量受限而需要高输出功率的问题。
The continuous worldwide demand for multi-Gb/s data-rate has driven the rapid development and standardization of 5G New Radio (NR) specifications in the mmwave bands [1-3]. As a result, there is a surge of interest in high-performance yet compact mm-wave 5G front-end chipsets to enable large-aperture phased arrays. In User Equipment (UE) devices, the limited form factor restricts the number of antenna array elements, e.g., 2×2, which dramatically increases the output power (Pout) requirement per element [1,4]. For base stations, although some applications require only moderate element Pout and high antenna gain, high Pout capabilities allow array-divisions/sub-arrays for concurrent multi-stream mmwave links. However, generating high Pout at mm-wave necessitates high-efficiency power amplifiers (PAs) and judicious power combining in low-breakdown silicon processes. A few silicon high-power (>26dBm Pout) mm-wave PAs have been
