摘要

摘要射频能量采集器是将环境射频电磁波转换为可用电能，在没有传统电源的情况下为低功率设备供电。本文提出了一种适用于700MHz频段的新型射频能量采集器。为了整流，电路中使用了Greinacher电压整流器兼乘法器，肖特基二极管HSM-2852用于实现整流器。实现LC阻抗匹配以提高采集器的电路性能，包括转换效率和输出电压。使用PathWave高级设计系统（ADS）软件对整流器进行了仿真。整流器在5kΩ负载阻抗下表现出最佳性能。仿真结果表明，在700MHz输入频率下，射频功率为8dBm时，最高效率为33.1%，输出电压为3.2V。

Design of RF energy harvester for 700 MHz

Abstract Radio frequency energy harvester is the conversion of ambient radio frequency electromagnetic waves into usable electrical energy, powering low-power devices without traditional power sources. In this paper, a novel RF energy harvester is proposed for 700 MHz frequency band. For the purpose of rectification, a Greinacher voltage rectifier cum multiplier is used in the circuit and Schottky Diode HSMS-2852 is used for implementing a rectifier. The LC impedance matching is implemented to improve the circuit performance of the harvester including conversion efficiency and output voltage. Simulation of the rectifier is done using the PathWave Advanced Design System (ADS) software. The rectifier shows the optimized performance at 5 kΩ load impedance. Simulation results show the highest efficiency of 33.1 % and an output voltage of 3.2 V with 8 dBm RF power at 700 MHz input frequency.
