标题： Simultaneous Switching of Multiple GaN Transistors in a High-Speed Switch

摘要： 用于费米实验室新PIP-II加速器的宽带行波kicker需要以80 MHz的重复率运行。 我们提出了一种技术，通过微波光子技术同时驱动四个串联连接的增强型氮化镓-硅功率晶体管。 这四个晶体管被配置成一个高压和高重复率的开关。 使用多个晶体管串联是为了分担开关损耗。 使用光信号分布系统是为了实现晶体管之间的精确同步。 我们展示了在200欧姆负载上生成600 V的任意脉冲，上升/下降时间为2 ns。 任意脉冲宽度可以从4 ns调整到几乎直流。 显示英文摘要

摘要： A broadband travelling wave kicker operating with 80 MHz repetition rates is required for the new PIP-II accelerator at Fermilab. We present a technique to drive simultaneously four series-connected enhancement mode GaN-on-silicon power transistors by means of microwave photonics techniques. These four transistors are arranged into a high voltage and high repetition rate switch. Using multiple transistors in series is required to share switching losses. Using a photonic signal distribution system is required to achieve precise synchronization between transistors. We demonstrate 600 V arbitrary pulse generation into a 200 Ohm load with 2 ns rise/fall time. The arbitrary pulse widths can be adjusted from 4 ns to essentially DC.
