本文介绍了两个宽带倍频器链（FMCs）与标准的130纳米SiGe BiCMOS工艺制造。在这两种解决方案中，采用了在220-360 GHz下工作的宽带推-推倍频器（x2）。为了适当地驱动这样的倍频器，具有足够的输入功率和带宽，已经采用了两种不同的功率放大器（PA）：前者基于共源共栅配置，后者基于堆叠拓扑。此外，在功率放大器和倍频器之前集成了一个D波段四倍频器（x4），完成了八倍频（x8）链的设计。采用共源共栅PA的第一个FMC实现了2.3 dBm的峰值输出功率，最大转换增益（G（C））和带宽分别为15 dB和127 GHz。采用堆叠式PA的第二个FMC提供2.5 dBm的饱和输出功率，最大G（C）和带宽分别为12 dB和72 GHz。这两种FMC的最大直流功耗分别为0.537和0.542 W。本文给出了FMCs的完整设计过程。据我们所知，所报道的带宽是最先进的，最宽的SiGe基FMCs。
This article presents two broadband frequency multiplier chains (FMCs) fabricated with a standard 130-nm SiGe BiCMOS process. In both solutions, a broadband push-push frequency doubler (x2) operating at 220-360 GHz was employed. In order to properly drive such a doubler, with sufficient input power and bandwidth, two different power amplifiers (PAs) have been adopted: the former is based on a cascode configuration and the latter is based on a stacked topology. In addition, a D-band frequency quadrupler (x4) has been integrated before the PAs and doubler, to complete the design of frequency eighth tupler (x8) chains. The first FMC with the cascode PA achieves peak output power of 2.3 dBm, with maximum conversion gain (G(C)) and bandwidth of 15 dB and 127 GHz, respectively. The second FMC with the stacked PA delivers a saturated output power of 2.5 dBm, with a maximum G(C) and a bandwidth of 12 dB and 72 GHz, respectively. The two FMCs consume maximum dc power of 0.537 and 0.542 W. The complete design procedure of the FMCs is presented in this article. To the best of our knowledge, the reported bandwidth is state-of-the-art and widest among SiGe based FMCs.
