Abstract

This work presents the design of a Dual Parallel RectiFier (DPRF) for Radio Frequency Energy Harvesting (RFEH) applications, capable of operating over a wide temperature range without decreasing its Power Conversion Efficiency (PCE) under low-power conditions. The proposed DPRF operates at the 3.5 GHz band, driven by the growing adoption of 5G applications in this frequency range and consisting of two parallel sub-rectifiers, one designed for 300 K using the SMS7630 Schottky diode and another for 345 K employing the SMS7621 diode. At an input power level of −20 dBm, the prototype demonstrated promising results for RFEH systems, maintaining a stable PCE over a wide temperature range, reaching 12.1% at 300 K and 9.0% at 345 K, demonstrating its potential to operate properly in environments with uncontrolled temperatures, making it suitable for a vast variety of industrial indoor or outdoor applications.

双并联射频整流器，宽工作温度范围，适用于sub-6 GHz 5G应用

本工作提出了一种用于射频能量收集（RFEH）应用的双并联整流器（DPRF）的设计，能够在低功率条件下在宽温度范围内工作而不降低其功率转换效率（PCE）。拟议的DPRF工作在3.5 GHz频段，受该频率范围内5G应用日益普及的驱动，由两个并联子整流器组成，一个设计用于300 K，使用SMS7630肖特基二极管，另一个设计用于345 K，使用SMS7621二极管。在−20 dBm的输入功率水平下，RFEH系统的原型显示出了良好的结果，在很宽的温度范围内保持稳定的PCE，在300 K时达到12.1%，在345 K时达到9.0%，证明了其在温度不受控制的环境中正常工作的潜力，使其适用于各种工业室内或室外应用。
