摘要

我们提出了一种用于小型蜂窝3G/4G基站的65nm直接转换接收器。该接收机支持高达100MHz的射频BW和400MHz至6GHz的载波频率,具有80dB的图像抑制和76dB的带内SFDR。直接转换架构消除了中频滤波,无需对图像和M×N混合产品进行射频滤波,从而减小了基站的尺寸和成本。

A direct-conversion receiver for multi-carrier 3G/4G small-cell base stations in 65nm CMOS
We present a 65nm direct conversion receiver for small cell 3G/4G basestations. The receiver supports up to 100MHz of RF BW and carrier frequencies from 400MHz to 6GHz, with 80dB image rejection and 76dB in-band SFDR. The direct conversion architecture eliminates IF filtering and the need for RF filtering of images and M×N mixing products, reducing basestation size and cost.
