Design of high-power dual-frequency rectifier circuit

The microwave wireless power transmission system avoids the problems of large consumables, complex construction, and high maintenance costs caused by the cable. It can be seen that this method has specific demands and is worthy of deep research. This paper designs a high-power dual-frequency rectifier circuit that works at 1.15 and 1.7 GHz for wireless energy transmission. Using GaN HEMT as the rectifier, the output DC power reaches 6.5W, far beyond the conventional diode rectifier circuit in terms of power capacity.
