Abstract:
A device for inductively coupled communications includes an NFC module for generating an electromagnetic carrier signal and modulating the carrier signal according to data to be transmitted, and a single ended antenna coupled to and driven by said NFC module with the modulated carrier signal. The device includes an RF front end coupled between said NFC module and said antenna. The RF front end includes an inductor coupled to a first terminal of a differential transmitter of said NFC module in the first transmitting path, and a capacitor coupled to a second terminal of said differential transmitter in the second transmitting path. The RF front end further includes a receiving path coupled to an input terminal of a single ended receiver of said NFC module. The RF front end does not use a balanced to unbalanced (Balun) transformer.

Claim (Index 8):
A device for inductively coupled communications comprising:\n a near field communication (NFC) module being adapted to generate an electromagnetic carrier signal and to modulate the carrier signal according to data to be transmitted, said NFC module including a differential transmitter and a single ended receiver; a singled ended antenna coupled to said NFC module and driven by said NFC module with the modulated carrier signal; and an RF front end coupled between said NFC module and said antenna; said RF front end including a first inductor coupled to a first terminal of said differential transmitter in a first transmitting path, and a first capacitor coupled to a second terminal of said differential transmitter in a second transmitting path; said RF front end further including a receiving path and a second capacitor, said second capacitor arranged in parallel and connected between an input terminal of the antenna and ground; wherein said differential transmitter of said NFC module operates with said single ended antenna without using a balanced to unbalanced (Balun) transformer; wherein said first inductor, said first capacitor, and said second capacitor being adapted to provide a function of an electromagnetic compatibility (EMC) filter without a dedicated LC pair coupled to each of said first terminal of said differential transmitter and said second terminal of said differential transmitter.
