摘要

提出了一种采用SiGe HBT技术实现的8.4-12.0 GHz下变频混频器。该混频器在工作频带内的转换增益为12.6 dB，回波损耗大于14 dB，噪声系数小于12.4 dB。在1.25 GHz的中频下，混频器还实现了-0.45 dBm的输入参考三阶截距点和2 dBm的输出1 dB压缩点，并且在3.0 V电源下，混频器核心仅耗散12 mW。这项工作还提出了一种新的混合器性能指标，以便更全面地比较不同技术和架构的混合器性能。

An 8.4-12.0 GHz down-conversion mixer implemented in SiGe HBT technology

An 8.4-12.0 GHz down-conversion mixer, implemented in SiGe HBT technology, is presented. The mixer achieves a conversion gain of 12.6 dB, a return loss greater than 14 dB, and a noise figure less than 12.4 dB over the band of operation. The mixer also achieves an input-referred third order intercept point of -0.45 dBm, and an output 1 dB compression point of 2 dBm at an IF of 1.25 GHz, and dissipates only 12 mW for the mixer core, off of a 3.0 V supply. This work also proposes a new mixer figure-of-merit to facilitate a more comprehensive comparison of mixer performance with varying technologies and architectures.
