The invention provides a data link radio-frequency system. The data link radio-frequency system comprises a local oscillation frequency source, a transmitting channel and a receiving channel, whereinthe local oscillation frequency source is used for generating two paths of first local oscillation signal and second local oscillation signal which are coherent with each other; the transmitting channel is used for performing frequency mixing on a signal input by a signal processor and the second location oscillation signal one after another, up-converting the mixed signal to a waveband of the first location oscillation signal, and outputting the mixed signal to an antenna; and the receiving channel is used for performing frequency mixing on a signal input by the antenna and the first local oscillation signal, down-converting the mixed signal to a waveband of the second local oscillation signal, and outputting the mixed signal to the signal processor. 本发明提供种数据链射频系统，包括本振频率源、发射通道和接收通道；所述本振频率源用于产生两路相参的本振信号和二本振信号；所述发射
