Abstract: A wireless communication device includes an antenna, a transceiver, a filter circuit and an attenuation circuit. The transceiver includes a transmission electrode and a receive electrode, and communicates with an external device through the antenna. The filter circuit is coupled between the transmission electrode and the antenna, and includes a harmonic trap circuit that eliminates a harmonic element of a carrier frequency of an outgoing signal provided from the transceiver through the transmission electrode. The attenuation circuit is coupled between the receive electrode and the antenna, and provides an incoming signal received through the antenna to the receive electrode after reducing a voltage of the incoming signal.

Abstract: A wireless power transceiver includes input generator, inverter, battery, antenna, impedance matching circuit, and mode voltage changer. The input generator outputs an input voltage as a primary input voltage and a secondary input voltage in a power transmitting mode. The input generator outputs a power supply voltage as a primary input voltage and outputs a ground voltage as a secondary input voltage in a power receiving mode. The inverter outputs to the second node, an inverted version of the input voltage in the power transmitting mode, and outputs to the first node, a rectified voltage of the second node in power receiving mode. The impedance matching circuit is connected between the second node and the antenna. The mode voltage changer converts a battery voltage of the battery to output the power supply voltage in the power transmitting mode, and charges the battery with a voltage converted from the power supply voltage in the power receiving mode.
