Abstract: A near field communication (NFC) device is disclosed which includes a NFC core communicatively coupled to an antenna module. The NFC core provides low power communication signals that traverse a sizable distance to an antenna module. The low power communication signals emit substantially less electromagnetic radiation when compared to high power communication signals that conventionally traverse this sizable distance. As a result, unwanted electromagnetic emissions and/or distortion impressed upon signals within other nearby electronic circuits are lessened. After the low power communication signals reach the antenna module, the antenna module converts the low power communication signals into high power communication signals for transmission to another NFC capable device. Additionally, the antenna module converts communications from this NFC capable device that are modulated onto the high power communication signals to provide the low power communication signals for the NFC core.
