Abstract

This paper investigates the RF energy harvesting performance of a test integrated circuit (IC), originally designed for 900 MHz, evaluating its metrics with a focus on power conversion efficiency (PCE) at a higher frequency of 2.45 within the widely used Industrial, Scientific, and Medical (ISM) frequency band. The focus is on RF energy harvesting applications for dedicated transmitters like RFID readers and mobile devices. A use-case targeted device was developed to analyze the maximum power point (MPP) across various RF operating points and DC load conditions, utilizing a digital potentiometer to emulate the DC output load with a strong focus on fast, flexible and precise measurements. Results demonstrate a maximum PCE of 25.9% in wired analysis and 11.6% in wireless experiments, emphasizing the feasibility of repurposing legacy RF energy harvesting devices for new frequency bands.
