摘要

本文描述了与高线性SiGe BiCMOS有源混频器相关的设计问题,主要针对WCDMA基站应用。描述了不同混频器组件对混频器整体动态范围的影响,并给出了四种不同实现的测量结果来支持这一讨论。不同的混频器作为一个完整接收器的一部分使用相同的过程实现,因此在性能分析中考虑了基带滤波器的接口。由于混频器设计的目标之一是最大限度地提高混频器带宽,因此本文讨论了不同替代方案的频率限制。

SiGe BiCMOS High Linearity Mixers for Base-Station Applications
This paper describes design issues related to high linearity SiGe BiCMOS active mixers, which are primarily targeted for WCDMA base-station applications. The effect of different mixer components to overall mixer dynamic range is described, and the measurement results from four different implementations are given to support this discussion. The different mixers are implemented using the same process as part of a complete receiver and thus the interface to baseband filter has been taken into account in the performance analysis. Since one of the goals in the mixer design has been to maximize the mixer bandwidth, the frequency limitations of different alternatives are discussed throughout the paper.
