Abstract
The application discloses a transceiver and a transceiver calibration method. The transceiver includes: a calibration signal generation unit for generating a first test signal and a second test signal to a transmission unit in a gain calibration mode; the transmission unit for generating a combined signal according to the first test signal, the second test signal and a transmission gain; a mixer for performing self-mixing upon the combined signal to generate a self-mixed signal; a receiving unit for generating a receiving signal according to the self-mixed signal; a Fourier transformer for computing a power of the receiving signal at a specific frequency; and a gain calibration unit for adjusting the transmission gain according to the power at the specific frequency in the gain calibration mode.
