本文提出一种小型化、高功率、宽带的太赫兹PA-天线阵列，采用0.13μm SiGe工艺，实现214-242GHz频段29dBm无透镜峰值EIRP。通过折叠10阶功率分配/合成和交错匹配方法，PA在160-248GHz达到17.4dB增益和16.5dBm饱和功率；集成共封装超低损耗缝隙贴片天线，辐射效率达66.7%，带宽36GHz。
Abstract This work presents a miniaturized, high-power, and wideband THz PA-antenna array, realizing 29dBm lens-less peak EIRP from 214 to 242GHz. To improve the BW and Psat of the PA, a folded 10th-order power-splitting/combining and staggered-matching method is proposed, achieving 17.4dB peak gain and 16.5dBm peak Psat from 160 to 248GHz. To address the efficiency and BW limitation of the AoC, a co-packaged ULP slot-patch antenna is integrated, extending the radiation efficiency to 66.7% and BW to 36GHz. The next generation of mobile and edge devices envision the convergence of ultra-highresolution sensing and imaging, integrated seamlessly into compact form factors such as smartphone bezels. This ambition necessitates a trend toward the terahertz (THz) band, where more spectrum resources could be allocated. Existing solutions, relying on bulky lenses, off-chip waveguides, or narrowband oscillator arrays, fail to meet the co-design
