摘　　要：A photonic-assisted radio frequency(RF)down-converter integrating with the optoelectronic oscillator(OEO)-based high quality local oscillator(LO)has been proposed and experimentally demonstrated.The LO and the RF input signal are mixed at the same phase modulator and photo-detector(PD)of the OEO-loop without any additional modulator or PD.The working bandwidth of the proposed RF down-converter is nearly from 2.5 to 10 GHz.The performance of the proposed down-converter is presented and the spurious frequency dynamic range at frequency of 5.5 GHz with the LO at 6.138 GHz is measured to be 98.4 dB–Hz2∕3.The influences that the frequency range and power of the RF input signal bring to the system are discussed as well.©2014 Chinese Laser Press.
