Abstract :
This work presents a description of a direct conversion transmitter excluding the power amplifier. The model predicts the impact of the even- and odd-order distortion introduced by the analog baseband signal processing and the mixer together with linear effects. The model is parameterized by measuring the response of a direct conversion transmitter onto single- and two-tone signals. By comparing the response of the transmitter to the model output the performance of the presented approach is verified.
