Abstract
Method and mixer using the method for mixing a complex digital input vector with an oscillator reference signal based on a separation of the mixing process in mainly two processing steps, to with a first step in which a set of n real part values V, is derived from said complex digital input vector in which n is an integer larger than 1 and in which each real part value Vis proportional to the real part of the digital input vector when being rotated over predetermined phase angles φ=φ+i*Δφ, respectively, for a constant φ, Δφ corresponding to either 2π/n or −2π/n, with integer i varying between 0 and n−1 and a second step, in which said n real part values and Vare each consecutively selected to be coupled to a load.
