Abstract:
A data transceiver device for near field communication is provided which includes a matching and filtering circuit connected between an antenna and a transceiver and configured to conduct filtering and impedance matching for a reception signal and a transmission signal. The matching and filtering circuit includes a variable attenuator of which the impedance varies with a frequency so that an attenuation ratio of the reception data is smaller than that of the reception carrier signal.
