    • A near-field wireless transceiver circuit includes: a transceiver-integrated circuit module; an antenna responding to a magnetic near-field; a filter circuit connected between the transceiver-integrated circuit module and the antenna, and an attenuation circuit connected between a receiver of the transceiver-integrated circuit module and the antenna. The filter circuit includes at least one stage of harmonic wave trap circuits connected in series to a transmission pass between the transceiver-integrated circuit module and the antenna. The attenuation circuit reduces a receiving signal to a first voltage level to apply it to a first receiving terminal of the transceiver-integrated circuit module in an active mode and reduces a receiving signal to a second voltage level which is less than the first voltage level to apply it to a second receiving terminal of the transceiver-integrated circuit module. Thus, a harmonic wave can be effectively removed by the harmonic trap circuits when transmitting, and optimized voltage attenuation can be done according to operation modes when receiving.
