现在的数字蜂窝标准对A/D转换器的动态范围性能有不小的压力。这使A/D转换器的选择受到限制，对少量所选择的A/D需要仔细评估其动态范围性能。对整个动态范围评估有影响的最重要因素是：所需的基带信噪比，无线电IF取样流的总谐波失真，无线电噪声因数，最坏情况下干扰和所希望 The current digital cellular standard exerts a tremendous pressure on the dynamic range performance of A / D converters. This limits the choice of A / D converter and requires careful evaluation of its dynamic range performance for a small number of selected A / Ds. The most important factors that affect the entire dynamic range evaluation are the required baseband signal to noise ratio, total harmonic distortion of the radio IF sample stream, radio noise figure, worst case interference and the desired
