Radio frequency transceiver system adopting dual-tone signal mixing

The invention belongs to the technical field of radio frequency transceiving systems, and provides a radio frequency transceiving system adopting dual-tone signal mixing, which comprises a transmitter and a receiver, and is characterized in that the transmitter comprises a transmitting baseband component which outputs dual-tone signals according to instructions; the transmitting channel component converts the dual-tone signal into a first intermediate frequency signal; the millimeter wave transmitting assembly converts the first intermediate frequency signal into a millimeter wave transmitting signal and then converts the millimeter wave transmitting signal into a self-checking signal; the receiver comprises a receiving millimeter wave assembly which receives a millimeter wave emission signal and converts the signal into an orthogonal intermediate frequency signal; the receiving channel component converts the orthogonal intermediate frequency signal into a second intermediate frequency signal; the receiving b
