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.
