ABSTRACT:
An apparatus and a method for cancelling distortion in a direct conversion receiver, such distortion created by the mixing of the desired signal with the output signal of an local oscillator. Subsequent to filtering the mixer output signal, the even mode distortion component is extracted, phase shifted, amplified and recombined with the mixed signal in such manner as to suppress even order distortion.
