Apparatuses, systems, and methods for correction of mismatches are provided, the apparatus including a signal generator to generate a signal for calibration for a radio frequency (RF) portion of a transmitter or an RF portion of a receiver of a direct-conversion architecture to calibrate for mismatches of in-phase and quadrature (I/Q) signals, at least one of the RF portions coupled by a loopback path, and the loopback path to couple first and second signals based upon the signal generated for calibration to the RF portion of the receiver, the loopback path including a phase-shifting module to shift the signal generated for calibration as propagated through a portion of the transmitter to generate the second signal with a different phase from the first signal, wherein the apparatus is configured to digitally correct mismatches of I/Q signals in the receiver and the transmitter based upon the first and second signals. |
