U.S.-U.K. Cooperative Research: Nonlinearities in MicrowaveControl Devices

该奖项将支持东南马萨诸塞大学的Robert Caverly博士和john博士之间的合作研究。克里斯托弗·斯诺登和迈克尔·豪斯，英国利兹大学电气与电子工程系。本计画的目的是研究微波控制装置的非线性。半导体器件目前在各种应用中被用于控制和开关功率和能量信号。理想情况下，这些器件在转换能量时不会将失真（由器件的非线性操作引起）引入电路或系统。然而，在实践中，失真的产生与被控制的信号直接相关。提出的研究工作是对影响这种信号失真产生的器件和电路参数进行研究。卡弗利博士对固态器件进行了广泛的理论建模。利兹微波固态集团不仅在这一领域，而且在电路和系统的建模和制造方面拥有丰富的经验。这些互补技能的结合将提供对无源和有源场效应晶体管电路性能的更好理解，特别是那些在单片微波集成电路中的应用。

This award will support collaborative research between Dr. Robert Caverly, Southeastern Massachusetts University and Drs. Christopher Snowden and Michael Howes, Department of Electrical and Electronic Engineering, University of Leeds, England. The objective of this project is a study of nonlinearities in microwave control devices. Semiconductor devices are presently being used to control and switch power and energy signals in a variety of applications. Ideally, these devices switch the energy without introducing distortion (caused by nonlinear operation of the devices) into the circuit or system. In practice, however, distortion is produced which is directly related to the signal that is controlled. The research work proposed is an investigation of the device and circuit parameters that will affect the generation of this signal distortion. Dr. Caverly has carried out extensive theoretical modeling of solid state devices. The Leeds Microwave Solid State Group has considerable experience not only in this area, but also in modeling and fabricating circuits and systems. The joining of these complementary skills will provide improved understanding of the performance of passive and active field effect transistor circuits, especially those in monolithic microwave integrated circuit applications.
