Abstract:
A radio frequency receiving link and a radio frequency transceiving device are provided. The radio frequency receiving link includes: an input unit, configured to input a first input signal; a clock unit, configured to generate a local oscillator signal; a receiving link frequency-mixing unit, configured to obtain the first input signal and the local oscillator signal, and generate a first frequency-mixing signal according to the first input signal and the local oscillator signal; and a calibration unit, configured to obtain first direct current offset information of the radio frequency receiving link, wherein the first direct current offset information is direct current offset information in the radio frequency receiving link when the receiving link frequency-mixing unit generates the first frequency-mixing signal.
