Nowadays, researches on microwave photonics become more and more important due to the needs for wideband and wireless multimedia. The typical utility system is the radio over/on fiber (ROF ) system. In the past few years, fiber Bragg grating (FBG) has been widely used due to its unique characteristic of wavelength selectivity. Hence, a variety of ROF devices based on FBG have become one of the best programs. In this paper, two kinds of microwave photonic filter are studied, the frequency responses are simulated and the perfect results are gotten. Besides, a method is proposed to realize millimeter-wave sub-carrier generation at central station by using a double-uniform FBG filter scheme. The advantages are analyzed by designing a ROF downlink system, and the eye diagrams in different transmission distance are also analyzed.
