该论文提出了一种60GHz片上线性辐射器，采用多馈天线技术实现单元素27.9dBm的饱和输出功率和33.1dBm的峰值等效全向辐射功率，旨在解决毫米波5G通信中高路径损耗和链路预算限制下的功率合成与线性度问题。
links, e.g., for the 5G communication, is to provide large transmitter (Tx) output power (Pout) with high energy efficiency and linearity from a limited supply voltage, so that the high path loss and limited link budget at mm-wave can be compensated. Power combining is often required for high-power mm-wave Tx. The existing powercombining techniques are mainly in two categories. Passive on-chip/on-package networks can combine Pout from multiple power amplifiers (PAs) and feed a single antenna port [1-4]. However, lossy power combiners and large impedance transformation ratios degrade the total Pout delivered to the antenna and lower the Tx efficiency. Alternatively, spatial power combining using antenna array increases the total EIRP but at the expense of a large array-panel size. Moreover, a large
