摘要
本文提出了一种基于氮化镓晶体管的双频同步整流器。为了提高整流器的效率，根据整流器的正负极性模式分析了双频移相网络。然后，利用由 L 型和 T 型网络组成的移相结构实现任意两个频率之间的移相差。我们制造出了工作频率为 0.905 和 2.4 GHz 的高效双频氮化镓同步整流器。此外，还利用号角天线构建了一个大功率无线电力传输实验系统。该系统由双频同步整流器、宽带功率放大器（PA）和一对波导输入型标准增益号角天线组成。测量结果验证了拟议系统的可行性。
Design of Dual-Band Synchronous Rectifier for High-Power Wireless Power Transmission System
This letter proposes a dual-band synchronous rectifier based on GaN transistors. To improve the efficiency of the rectifier, a dual-frequency phase-shifting network is analyzed based on the positive and negative polarity modes of the rectifier. Then, the phase shift difference between any two frequencies is realized using a phase-shifting structure consisting of L- and T-type networks. A high-efficiency dual-band GaN synchronous rectifier operating at 0.905 and 2.4 GHz is fabricated. In addition, a high-power wireless power transmission experimental system was constructed using horn antennas. The system consists of a dual-band synchronous rectifier, a broadband power amplifier (PA), and a pair of waveguide input-type standard gain horn antennas. Measurement results verify the feasibility of the proposed system.
