Abstract:
An apparatus and a method. The apparatus includes a first low pass filter (LPF), a second LPF, a first analog-to-digital converter (ADC), a second ADC, a first discrete Fourier transform (DFT) unit, a second DFT unit, a second order intermodulation (IM2) tone amplitude measurement unit, and a calibration logic unit configured to simultaneously determine an in-phase mixer (I-mixer) digital-to-analog (DAC) code and a quadrature-phase mixer (Q-mixer) DAC code.
