A novel rectifying circuit with circulator in microwave power transmission

摘要

A novel rectifying circuit is developed at large dynamic input power conditions. This rectifying circuit utilizes the circulator in which the microwave is constrained to travel one-way. The reflected microwave caused by mismatch is lead to next rectifying circuit and the conversion efficiency is guaranteed 54%. The power conversion efficiency (PCE) is achieved at 20dBm input power condition. The experiment results demonstrate the PCE of this novel rectifying circuit is more stable than traditional rectifying circuit at large dynamic input power conditions.
