This work presents an ultra-wideband, balanced frequency multiplier and amplifier combination, implemented in a 130 nm SiGe BiCMOS process. A design technique for balanced, extreme bandwidth frequency multiplier is introduced. The topology is then combined with an inductively peaked, differential wideband amplifier to address the required bandwidth, the output power and to suppress the common mode signal. The designed circuit operates in a continuous 3 GHz to 40 GHz output frequency range, has an average conversion loss of 3 dB, the rejection ratios of fundamental and 3rd harmonic frequencies are better than 34 dBc and 48 dBc respectively and it consumes 21 mA from a 3 V power source. To the best knowledge of the author, this work strongly outperforms the state of the art in terms of the fractional bandwidth.

Nowadays, there are a variety of different indoor positioning systems employing diverse techniques. On promising approach is Frequency Modulated Continuous Wave- (FMCW) radar, where in addition to several custom approaches, there already exist commercial ICs. Within this work, we are targeting the extension of these systems towards integrating phase measurements with the ultimate goal to improve accuracy. Initially, we present the underlying math for different hardware settings. Subsequently, we focus on our custom FMCW-radar system and analyse the prerequisites for an integration. It becomes clear that already moderate synchronization jitter of 15 mu s together with frequency deviations caused by an excellent 20 MHz crystal exhibiting 3 ppm influences operability. We describe our experiments and highlight modifications to establish the principle on the given hardware. Ultimately, this paper contains many lessons learned to simplify the development of similar systems.

In this presentation it will be discussed how to obtain analytical or quasi-analytical equivalent circuits to deal with periodic structures such as frequency selective surfaces and/or metasurfaces. Both the topology and the values of the involved elements of these circuits are obtained from a basic rationale to solve the corresponding integral equation. This procedure, besides providing a very efficient analysis/design tool, allows for a good physical insight into the operating mechanisms of the structure in contrast with the almost blind numerical scheme of commercial simulators.
