Large signal rectifier characterization for simultaneous data and Power Transfer

In this work we characterize the RF-to-baseband response of a diode used for a rectifier circuit. The measurement setup enables the synchronous acquisition of vector-calibrated baseband and RF time-domain waveforms. The behavior of a Schottky diode, widely employed for RF Energy Harvesting and Wireless Power Transfer applications, is first measured, then further optimized, in order to enable the level of accuracy needed for the correct decoding of a possible modulated input RF signal. Finally, the RF to baseband response is further validated with a single-stage rectifier, in a different measurement setup.
