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 near field communication (NFC) device includes a resonance unit and an NFC chip. The resonance unit emits an electromagnetic wave to communicate data with an external NFC card in a reader mode. The NFC chip estimates a distance between the resonance unit and the external NFC card based on an antenna voltage generated by the resonance unit while the resonance unit emits the electromagnetic wave, and adjusts a magnitude of the electromagnetic wave based on the estimated distance.
