主权项

1. A device, comprising:
an antenna configured to transmit and receive near-field communication signals and to couple to at least two inputs and to at least two outputs of a near-field communication controller; a first spectrum spreading element coupled between the antenna and a first input terminal of the near-field communication controller; a second spectrum spreading element coupled between the antenna and a second input terminal of the near-field communication controller; a first resistive element coupled in parallel with the first spectrum spreading element; a second resistive element coupled in parallel with the second spectrum spreading element: and a low-pass filter at each of the at least two inputs of the near-field communication controller.
