The goal of the challenge was to design an algorithm for pre-distorting a 2-channel MIMO transmitter with cross-coupling effect in order to maximize the linearity of the overall system. The system consisted of two GaN HEMT Doherty power amplifiers and a coupler to control the crosstalk between the two PAs. The team implemented a cascaded polynomial model that reduced unwanted static and dynamic effects as well as crosstalk between the two PAs, optimizing the overall performance of the system.

    @inproceedings{schrotz2019,
    abstract = {In this paper, a design methodology for automated Marchand balun design is shown. The goal of this methodology is a balun providing the lowest insertion loss at the smallest phase imbalance. The design process is realized by using the EM simulator Sonnet, Matlab and the Matlab-Sonnet interface. The implemented algorithm is using a simulation-based characterization of the semiconductor process and a mathematical model of the balun. For this characterization an even and odd mode analysis is carried out. Hence, the electrical and dielectric properties, such as the characteristic impedance and the effective permittivity, are determined. This enables a precise "first guess simulation" of the balun, minimizing the required number of optimization iterations. As an example, a D-band Marchand balun is presented here, that was designed with this methodology. The measurement results show a phase imbalance less than 7° over the entire D-band and an insertion loss smaller than 1.75 dB. To the best of the author's knowledge, there was no software tool that enables automated development for Marchand baluns yet, although it is widely used.

    abstract = {The rapid proliferation of smartphones, tablets, and intelligent wearables is proof of the global success of high-performance RF acoustic devices based on bulk acoustic wave (BAW) and surface acoustic wave (SAW) technologies. Advanced wireless communication standards, such as 4G/LTE and the upcoming 5G, make the implementation of new RF features (power handling, wider bandwidth, and reconfigurability) mandatory in modern end-user equipment for mobile communications. This leads to an increasing demand for SAW and BAW components due to their compatibility with higher frequencies. In the year 2020, shipments of RF filters will exceed 68 billion (Figure 1), of which about 40 billion will be high-performance filters, such as film bulk acoustic resonators (FBARs), high quality factor (Q) BAW components, temperature-compensated (TC) SAW components, and thin-film SAW components [1]-[3].},

    @inproceedings{pfeiffer2019,
    abstract = {Differences in contact impedance of the ECG measurement electrodes lead to asymmetries of the signal paths and thus result in reduced common-mode rejection and artifacts. Here, the imbalance of contact impedance is investigated for different types of electrodes with capacitive coupling in terms of static imbalance as well as dynamic variation during body movement. Flexible and incompressible materials like conductive foam and fabric showed the best overall performance. The negative effect of rigidity can partly be compensated by adding conducting foam, while soft materials can profit from an increase of electrode area.
