The department "Mixed Signal Circuit Design" (MSC) at the Technische Universität Berlin, headed by Prof. Dr.-Ing. Friedel Gerfers, develops circuits and systems for wired and wireless high-speed communication as well as automotive applications with its research groups "Wireline Communication Systems" and "Wireless Communication Systems". Current projects include complete transceivers as well as transceiver components - with data converters as the core competence.Wired projects include transceivers with data rates of up to 224 Gbit/s (112 GBaud PAM4) and components such as VCSELs and optical modulators with symbol rates of up to 150 GBaud to advance the development of current and future transmission technologies in data centers (400 and 800 Gigabit Ethernet). Wireless frequency ranges up to the D-band (with up to 170 GHz) are used for communication systems to be developed with data rates of more than 100 Gbit/s, in particular for the next mobile phone generation "6G". In order to have the characterization capabilities needed for this research, this proposal requests a W- and D-band spectral measurement setup (“W- und D-Band Spektralmessplatz (75-170 GHz)”) and, in a parallel proposal, a 100 GHz real-time measurement setup (“100 GHz Echtzeitmessplatz”).The main components of the W- and D-band spectral measurement setup (75-170 GHz) consist of frequency modulators for the W- and D-band. These modulators, together with the also requested accessories and with an existing S-parameter measurement setup („S-Parametermessplatz“), enable measurements in the corresponding frequency ranges. The existing S-parameter measurement setup consists in particular of a vector network analyzer as well as a mm-wave wafer prober and was funded by a previous major research instrumentation proposal in 2019. However, at that time there was neither the project need nor the funding possibility for the extension to W- and D-band. The current need for the extension to W- and D-band, as well as the applications of the existing S-parameter measurement setup that took place so far are presented in this proposal.The W- and D-band spectral measurement setup (75-170 GHz) is needed in the mentioned current research e.g. to measure matching, gain, bandwidth, transmission behavior as well as compression and intermodulation behavior of amplifiers (e.g. LNA, PA, TWA, TIA). In addition, components such as VCSELs, VCSEL drivers, DACs, AFEs and transmission channels are characterized in terms of matching and bandwidth - also to optimize modeling for the development of corresponding components and entire associated systems. Depending on the application and research project, these components and overall systems operate in frequencies up to 120 GHz (incl. W-band) or 110 to 170 GHz (D-band), which is why the corresponding frequency modulators with accessories are needed and requested in this proposal as W- and D-band spectral measurement setup (75-170 GHz).

柏林理工大学“混合信号电路设计”(MSC)系由Dr.-ing教授领导。Friedel Gerfers与其研究小组“有线通信系统”和“无线通信系统”一起开发用于有线和无线高速通信以及汽车应用的电路和系统。目前的项目包括完整的收发信机和收发信机组件--以数据转换器为核心能力。有线项目包括数据速率高达224 Gbit/S(112 Gbaud PAM4)的收发信机，以及符号速率高达150 Gbaud的VCSEL和光调制器等组件，以推动数据中心(400和800千兆以太网)当前和未来传输技术的发展。无线频率范围可达D波段(最高可达170千兆赫)，用于将要开发的数据速率超过100Gbit/S的通信系统，特别是下一代手机“6G”。为了具有这项研究所需的表征能力，本提案要求W和D频段的光谱测量设置(“W-und D-Band SpektralMessPlatz(75-170 GHz)”)和一个并行的100 GHz实时测量设置(“100 GHz EchtzeitMessPlaz”)。W-和D-频段的频谱测量设置(75-170 GHz)的主要组件包括W-和D-频段的频率调制器。这些调制器，连同同样需要的附件和现有的S参数测量装置(“S参数信息平台”)，可以在相应的频率范围内进行测量。现有的S参数测量装置尤其由矢量网络分析仪和毫米波晶片探测仪组成，并由2019年之前的一项重大研究仪器提案提供资金。然而，当时既没有项目需要，也没有扩展到W-波段和D-波段的资金可能性。本文介绍了目前扩展到W和D频段的需求，以及目前已有的S参数测量装置的应用。在上述研究中，需要W和D频段的频谱测量装置(75-170 GHz)，例如测量放大器(如低噪声放大器、功放、行波放大器、行波放大器)的匹配、增益、带宽、传输行为以及压缩和互调行为。此外，VCSEL、VCSEL驱动器、DAC、AFE和传输通道等组件在匹配性和带宽方面也具有特征，这也是为了优化相应组件和整个相关系统的开发建模。根据应用和研究项目的不同，这些组件和整个系统的运行频率高达120 GHz(包括这就是为什么需要相应的频率调制器及其附件的原因，并在本提案中要求作为W和D频段的频谱测量装置(75-170 GHz)。
