Abstract
A transceiver circuit includes a transceiver antenna, a transmitter circuit, a receiver circuit, a frequency synthesizer and a baseband circuit. The transmitter circuit transmits a radio frequency signal corresponding to a radio frequency through the transceiver antenna. The frequency synthesizer provides a first local oscillation signal and a second local oscillation signal having a first local oscillation frequency and a second local oscillation frequency, respectively. The baseband circuit operates in a transmitting mode and a receiving mode. In the transmitting mode, the frequency synthesizer provides the first local oscillation signal, and in the receiving mode, the frequency synthesizer provides the second local oscillation signal, the first local oscillation frequency is a non-integer multiple of the radio frequency, and the second local oscillation frequency is an integer multiple of the radio frequency.
