摘要
设计实现了一种基于微带结构的微波整流电路,研究了在不同输入功率下的微波整流效率.该整流电路采用肖特基二极管的倍压式整流电路设计,针对输入微波功率的大动态范围进行了优化设计.通过软件仿真和加工实测,表明在0 dBm至20 dBm的微波输入功率下,该整流电路均可获得不低于50%的直流转换效率.在17 dBm的微波输入功率下,整流电路效率达到了78.8%.
A microwave rectifier based on microstrip structure is designed and realized in this paper. The microwave rectifying efficiency dependent on microwave input power is studied. The microwave rectifier is based on a voltagedoubler circuit with two series diodes. It has been optimized for high dynamic range of microwave input power. Simulations and measurements show that the rectifying efficiency is higher than 50% at microwave input power from 0 dBm to 20 dBm. The highest conversion efficiency is 78.8%, when the input microwave power is 17 dBm.
