摘要
为了使无线通信系统短距离数据传输速率达到10Gbit/s,利用光电结合技术以THz波段为载波,建立了太赫兹无线通信系统。为提高无线通信系统的传输距离,设计了带有高增益天线和波导输出光电二极管模块的光学发射器。模块采用载波单向导通光电二极管、宽带高电子迁移率晶体管放大器和平面电路-波导转换衬底等技术。并对适合分析太赫兹波段发射器透镜天线的射线追迹法进行分析。仿真结果显示:该WG-PM在125GHz时最大输出功率为8dBm,3dB带宽大于16GHz。
In order to increase the short -distance wireless data transfer rate to 10 Gbit/s, a THz wireless communication system adopting photo electricity technology was built. In which, the optical emitter designed with high- gain antenna and waveguide output photodiode module （WG- PM ） helped to improve the systematic transmission distance. WG - PM was composed of uni - traveling - carrier photodiode（ UTC - PD）, broadband high electron mobility transistor（HEMT） amplifier and planar- circuit- to- waveguide transition substrate. It analyzed optical ray tracing method that fit for lens antenna of terahertz radiation emitter. The simulation results show： the WG - PM can output maximum power to 8 dBm in 120 GHz with bandwidth over 16 GHz/3 dB.
