Receiver I/Q group delay mismatch correction

A device for minimizing group delay mismatch in a quadrature receiver (402) having an in-phase channel and a quadrature-phase channel. The device includes a microprocessor (465) for determining an I/Q phase imbalance between digital signals on an in-phase channel and digital signals on a quadrature-phase channel, and for calculating a group delay mismatch between the in-phase channel and the quadrature-phase channel, and a group delay equalizer (426). The group delay equalizer includes a delay line (505 and 605) for delaying one of the in-phase channel and the quadrature-phase channel by one of a plurality of delays, based on an amount of group delay mismatch.
