  • Method for performing dual mode image rejection calibration in a receiver
    Patent number: 8150358
    Abstract: A method is disclosed for performing dual mode image rejection calibration in a receiver. A first image correction factor is acquired using a first known signal associated with a first signal band during a startup mode. The first image correction factor has a plurality of bits including most significant bits (MSBs) and least significant bits (LSBs). The LSBs of the first image correction factor are adjusted incrementally during a normal operation mode. A radio frequency (RF) signal associated with the first signal band is received using the first image correction factor during the normal operation mode.
