Abstract
A near field communications (NFC) transponder includes a transmit circuit coupled to a transmit antenna and a receive circuit coupled to a receive antenna. The transmit/receive antennae are configured such that no signal is induced on the receive antenna by operation of the transmit antenna. Advantageously, this permits continued reception by the receive antenna while the transmit antenna is used for transmission using active load modulation.
