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.

RFID transceiver with implemented phase calibration, and phase calibration method

There is described a radio device comprising:

Radio device with DC/DC converter and phase calibration

An RF receiver comprising: an amplifier configured to receive an RF signal over an input bandwidth and to provide an amplified RF signal; an equalizer circuit connected to the amplifier to receive the amplified RF signal and configured to provide an equalized RF signal; a converter module connected to the equalizer circuit and comprising an analog to digital converter configured to convert the equalized RF signal to a digital signal; and a digital signal processing module connected to the receiver module and configured to process the digital signal to provide a plurality of channels at an output of the receiver, wherein the digital signal processing module is further configured to process the digital signal to determine a measure of tilt in the RF signal across the input bandwidth and is connected to the equalizer circuit to provide a control signal for adjusting the measured tilt.
