Abstract
There is described an RFID device, comprising: a transmitter, a matching device, and a receiver. The transmitter is hereby coupled via the matching device to the receiver. The transmitter is configured to transmit a transmitter signal through the matching device, thereby obtaining a calibration signal. The receiver is configured to receive the calibration signal and estimate a phase shift of the calibration signal. Further, the RFID device is configured to adjust at least one of a transmitter phase shift and a receiver phase shift in order to compensate for the estimated phase shift. Further, a method of calibrating a phase shift in an RFID device is described.
