Abstract
Devices and methods capable of correcting for distortion are disclosed. For example, a method for compensating for non-idealities in a frequency-conversion circuit having a high-frequency input side separated from a baseband side by a passive mixer is presented. The method includes injecting a plurality of calibration signals in the baseband side to determine cross-talk between an In-phase (I) portion of the baseband side and a Quadrature (Q) portion of the baseband side to produce a first measurement Γand a second measurement Γ, synthesizing a crosstalk compensation filter g(ω) based on the first measurement Γand the second measurement Γ, and applying the crosstalk compensation filter g(ω) to an output of the frequency-conversion circuit.
