Abstract: The present disclosure provides a transmitter, a transceiver and a signal transmission method thereof. The transmitter comprises a signal amplification module, a balun and a feedback current generation module; the signal amplification module is configured to receive an input signal, amplify the input signal and output a differential signal to the balun; the balun is configured to receive the differential signal and convert the differential signal into a single-ended signal; and the feedback current generation module is configured to form electromagnetic coupling with the balun to generate a feedback current signal, wherein the feedback current signal is used as an input signal to a receiver.
