This paper describes two RF architectures applicableto Software Defined Radios: zero-IF and low-IF. Thefundamental principles, as well as the main advantages anddrawbacks, are presented. Both architectures have beencompared by means of simulated data, which take into accountlinear and no-linear distortion effects. The results show that thelow-IF architecture presents better performance than the zero-IF.
