“…The coupler port is then acquired by the receiver, which gives information about the multi-sine signals that are read in real time. The dc voltage of the device is thereafter read, and the effi ciency is consequently calculated, using Equations ( 1) and ( 2) [8,9]:…”

The main obj ective of this work is to present a characterization system capable of generating diff erent multi-sine signals to optimize the performance of RF-dc converters. The system allows the measurement in real time of the effi ciency of the RF-dc converters, according to diff erent multi-sine signals that are generated by using LabVIEW.In Int er net of Things (IoT) environments, wireless power transfer (WPT) assumes an important role, and RF-dc converters are one of the key technologies for this purpose. Consequently, it is very important to characterize and measure the wireless power transfer devices in order to enhance their behavior and also to improve their performance in 5G scenarios.

“…In [4], the author shown how the use of waveforms specifically selected or conceived in WPT systems can lead to better RF-DC conversion efficiency. Moreover, in [5] the authors described the behavior of rectifier RF-DC subjected to high RF input power. The efficiency degrades in the high input power region, typically for a power above -10 dBm.…”

In this paper, the authors are proposing a way to maximize the DC power collected in the case of a wireless power transfer (WPT) scenario. Three main aspects are taken into account: the RF (radio frequency) source, the propagation channel and the rectifier as the main part of the energy collecting circuit. This problem is formulated as a convex optimization one. Then, as a first step towards solving this problem, a rectifier circuit was simulated by using Keysight's ADS software and, by using a classical model identification strategy i. e. Vector Fitting (VF) algorithm, the state-space model of the passive parts of this rectifier were extracted. In order to verify the extracted model, S 11 input reflection coefficients and DC output voltages of the original circuit and the state-space model are compared.
