本文介绍了几种使用不同二极管的整流器。整流器的设计和测试适用于高功率输入射频条件。测试电路设计在2.45 GHz工作频率下，采用径向桩实现，以获得最佳匹配条件。为了抑制高次谐波，这里使用了F类设计方法。结果证实，整流器有效地将射频功率转换为可用的直流功率范围内的射频功率值。请注意，文献中很少有研究比较目前可用的用于射频整流应用的现成二极管，这使得本文成为高效远场无线电力传输系统的有价值的设计工具。
several rectifiers using different diodes are presented in this work. The rectifiers are designed and tested for high power input RF conditions. The tested circuits are designed for 2.45 GHz of operating frequency, and implemented with radial stubs to obtain optimum matching conditions. The class- F design methodology is used here in order to suppress higher order harmonics. The results confirm that the rectifiers are efficiently converting the RF power in to usable dc power for a range of RF power values. Note that there are very few studies in the literature comparing currently available off the shelf diodes for RF rectification applications, making this paper a valuable design tool for efficient far field wireless power transfer systems.
