提出一种采用马赫增德尔干涉仪（MZI）产生光载毫米波的光纤无线通信（ROF）系统。该系统采用基带信号与本振信号的混频信号驱动光相位调制器，以产生多边带光信号，用MZI将多边带光信号的重复频率增至2倍。建立了产生光载毫米波的理论模型，并通过仿真试验验证了系统的可行性。结果表明：用40GHz光载毫米波调制2．5Gbit／s基带信号，经60km光纤传输后，眼图清晰可见，功率代价为4．2dB。

Proposes a radio-over-fiber system through MIZ generating optical mm-wave. The system applies the mixed-frequency signals with base-band signals and LO signals to drive an optical phase modulator for generating multiple sidebands optical signal. Uses MZI to increase the optical signal with double frequency. Establishes the theoretical model for producing optical mm-wave and verifies the feasibility of the system through simulation test. The result shows that the 2.5 Gb/s base-band signal modulated by 40GHz optical mm-wave is visible on eye diagram after 60 km fiber transmission with 4.2dB power penalty.
