<p>A radio frequency (RF) transceiver is provided. The RF transceiver comprises a transmit path comprising an output coupled to an RF antenna, a feedback path comprising an input coupled to the output of the transmit path, and a DC offset calibration module comprising a first input coupled to an output of the feedback path, a second input to receive a first signal and an output connected to an input of the transmit path. The DC offset calibration module is operable to determine a first direct current (DC) offset of a closed-loop path comprising the transmit path and the feedback path and determine a second DC offset based on the feedback path exclusive of the transmit path.</p> |
