介绍了一种新型的W波段有源负载拉动系统。它是第一个通过利用变频技术的有源环路实现94 GHz负载的负载-拉动系统。有源环路配置展示了许多优势，它们以经济高效的方式克服了W频段无源调谐器或传统有源开环技术的典型限制：在94GHz时，负载反射系数ΓL可高达0.95千兆赫，从而几乎完全覆盖了史密斯图。该装置的可能应用包括技术评估、亚太赫兹频率下的大信号器件模型验证以及W频段单片微波集成电路的设计和表征。W波段的直接和准确的负载-拉力测量的可用性应该被证明是亚太赫兹集成电路开发中的一项资产。首先介绍了对高性能InP双异质结双极晶体管和GaN高电子迁移率晶体管的测量结果。
A new W-band active load-pull system is presented. It is the first load-pull system to implement a 94 GHz load by means of an active loop exploiting frequency conversion techniques. The active loop configuration demonstrates a number of advantages that overcome the typical limitations of W-band passive tuners or conventional active open-loop techniques in a cost-effective way: load reflection coefficients ΓL as high as 0.95 in magnitude can be achieved at 94 GHz, thus providing a nearly full coverage of the Smith chart. Possible applications of the setup include technology assessment, large-signal device model verification at sub-terahertz frequencies, and W-band monolithic microwave integrated circuit design and characterization. The availability of direct and accurate load-pull measurements at W-band should prove an asset in the development of sub-terahertz integrated circuits. First measurements performed on high-performance InP double heterojunction bipolar transistors and GaN high electron-mobility transistors are presented.
