摘要：A data transceiver device for near field communication is provided whichincludes 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 atransmission signal. The matching and filtering circuit includes a variable attenuator ofwhich the impedance varies with a frequency so that an attenuation ratio of the receptiondata is smaller than that of the reception carrier signal.
