In order to adapt the development from the mpm to the mmpm , this paper has done some exploringly research on the milli - meter wave equalizer and proposed a circuit template that can carry the power equalizer in ka band out . this thesis has proved the feasibility of realizing the milli - meter wave power equalizer used this circuit template by the way of computer simulation and experiment , and finally concludes a useful method for designing the milli - meter wave power equalizer 为了适应微波功率模块mpm向毫米波功率模块mmpm的进一步发展,本论文对毫米波功率均衡器进行了探索性的研究,提出了一种在ka波段实现功率均衡器的电路拓扑,并用计算机仿真和实验证明了此种拓扑结构实现毫米波功率均衡器的可行性,最终归纳出一种切实可行的毫米波功率均衡器的设计方法。
As a new kind of microwave power modules , a mpm consisting of a broad - band twt , a solid - state power driver and an integrated power conditioning , is a very important part in a next - generation electronic military system , and the milli - meter wave power module ( mmpm ) will be well developed as follows 微波功率模块mpm作为一种新型的微波功率部件,由宽带行波管、固态功率放大驱动模块和集成电源构成,在新一代电子战系统中具有重要的意义,并逐渐向毫米波功率模块( mmpm )方向发展。
Above all , we introduce the development of millimeter - wave power combiner and the novel study production at home and abroad . taking circuit form into consideration in the design of millimeter - wave power combiner , the gauge of high reliability and high performance must be defined . we design two kinds of waveguide - to - microstrip transition , the first kind of transition based on the achievement of a matched impedance probe show excellent performance , the second transition can also have good performance on some conditions through numerical simulation 介绍了国内外毫米波功率合成的发展状况和最新的研究成果。考虑拟以电路合成方式做毫米波功率合成器,必须解决与功率合成有关的相关组件的高可靠高性能指标问题,因此设计了两种波导微带过渡结构,其中探针式过渡测试达到了较好的效果,并对所提出的一种新型微带波导过渡进行了仿真,在一定条件下具有较好的性能。
Wave energy is the transport of energy by ocean surface waves, and the capture of that energy to do useful work ? for example, electricity generation, water desalination, or the pumping of water (into reservoirs). Machinery able to exploit wave power is generally known as a wave energy converter (WEC).
