Abstract:
     A method, of reducing distortion due to a third order intermodulation (IM 3 ) product, may include: receiving an original signal; and performing, before frequency translation is done to the original signal or a version thereof, steps that include the following, firstly manipulating the original signal to form a first manipulated signal that includes a first IM 3 product, secondly manipulating the original signal to form a second manipulated signal that includes a second IM 3 product, and combining (A) one of the first manipulated signal or a version thereof having substantially the same frequency with (B) one of the second manipulated signal or a version thereof having substantially the same frequency such that the second IM 3 product is used to substantially counteract the first IM 3 product.
