A methed to generate millimeter(mm)-wave using only one single-electrode Mach-Zehnder modulator (SD-MZM) was proposed and theoretically analysised. To generate a mixing signal, the baseband signal is mixed with the radio signal using an electric mixer. And the double-sideband(DSB) signal generated from SD-MZM drived by the mixing signal is transmited to base station(BS) over fiber. The optical carrier of the DSB signal which can be reused for uplink connection and the first-order optical sidebands of the DSB signal which generates the millimeter-wave are separated by an optical interleaver (IL) at base station(BS). The dispersion performance of the millimeter-wave is analyzed systematically by theory and simulation. According to theory and simulation results, the different delay of two first sidebands due to the fiber dispersion leads to power loss of mm-wave and the inter-symbol interference(ISI) of demodulated signals, so it limits the maximum propagation distance of mm-wave.
