This article presents a 5.2 GHz high‐efficiency rectifier, based on a Class‐F Dickson charge pump, for use in RF energy harvesting systems. A single‐stage Dickson charge pump with two Schottky diodes was adopted to produce a high‐output DC voltage. A harmonic source‐pull simulation was conducted to optimize the third harmonic impedance for the Class‐F harmonic termination. The proposed scheme is verified by designing and implementing a hybrid Class‐F Dickson charge pump for the 5.2 GHz band using two Schottky diodes in a package. The proposed rectifier has a very small size of 19 18 mm 2 , and the implemented rectifier exhibited a high RF‐to‐DC conversion efficiency of 64.1% and an output DC voltage of 5.1 V at an input power of 24 dBm for the 5.2 GHz single‐tone signal.
