Abstract :
Ultra-Wide Band radio-over-fiber (UWBoF) techno-logy involves two kinds of communications. One is the UWB wireless communication, and the other is optical fiber communi-cation. In this paper, the UWBoF receiving system based on the external modulation such as Mach-Zehnder (M-Z) modulator is analyzed. The UWBoF components and the UWBoF receiver structure are introduced. The received high frequency UWB signal by UWB antenna has been transformed into the low frequency which could be fit the frequency requirement for the RF port of the M-Z modulator. The electronic signal can be transformed into the optical signal and transmit in optical fiber by M-Z modulator. Firstly, the characteristics of M-Z modulation are analyzed in theory. Then the half-wave voltage and the modulation output spectrums characteristics of the UWBoF receiving system have been tested. The testing results show that the output spectrums characteristics are consistent with the theoretical analysis.
