Abstract

A method is disclosed for performing dual mode image rejection calibration in a receiver. A first image correction factor is acquired for use in a receiver system using a first known signal associated with a first signal band during a startup mode. The first image correction factor is 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.
