摘要 搭建了一种基于光载波抑制产生6倍频毫米波的RoF系统。系统采用马赫-曾德尔强度调制器(MZM)和滤波器抑制了偶次和一阶光边带,2个三阶光边带在基站端的光电检测器中进行拍频,得到了6倍频毫米波信号。仿真结果表明,采用10 GHz的微波信号,可以产生60 GHz的毫米波,2.5 GB/s的信号可以在单模光纤中传输15 km以上。 A scheme of RoF system based on optical carrier suppression to generate frequency-sextupled millimeter-wave effec- tively is demonstrated. A Mach-zehnder intensity modulator（ MZM ） and an optical filter are equipped to produce a signal whose even- order and first-order sideband is suppressed by adjusting the bias voltage of MZM. The signal is transmitted to the base station（BS）. In BS,two third-order sidebands beat to generate optical millimeter-wave with sextuple frequency in the photoelectric detector. Simulation results show that the 60 GHz optical millimeter-wave can be generated by 10 GHz RF resource. The eye diagram proves that the 2.5 GB/s data is successfully transmitted over 15 km single-mode fiber.
