摘要
通过理论建模,在中心站利用两级平行的马赫-增德尔调制器(Mach-Zehnder modul at or,MZM)组成一个光载毫米波倍频传输系统,两级MZM的射频驱动信号相位相差为45°。在基站利用PIN光电探测器对光信号进行直接探测,得到了纯度较高且频率为射频驱动信号频率8倍的毫米波信号。
Through theoretical modeling, an optical millimeter wave frequency system is established in the central station by using two stage parallel Mach-Zehnder Modulator (MZM), whose RF drive signal phase dif- ference is 45 degree. High purity millimeter wave signal whose frequency is eight times than RF drive signal is obtained by using PIN Photoelectric detector on the base station..
