Abstract

In the fields of ultra-wideband satellite communication, integrated radio frequency, radar and other national defense and military at present, it is necessary to realize the interconversion between baseband signals and radio frequency signals in Ka or even U band and L band to meet the processing requirements of RF front-end. Traditional electronic technology usually uses multistage local vibration mixing to realize frequency conversion, which is complicated and accompanied by serious nonlinearity and noise accumulation. As a kind of multi-wavelength light source, optical frequency beam can provide stable multiple local oscillations in the optical domain, and move the baseband/RF signals to the optical domain to achieve flexible mixing processing. In this paper, an UWB microwave photonic mixing technology based on optical frequency comb is innovatively proposed. UWB octave-spanning up-conversion from 10MHz to 60.01 GHz and down-conversion can be achieved by using only 20 GHz microwave driver, which effectively improves the RF preprocessing capability of UWB transmitter in the field of national defense and military.
