  1. Taking the IoT’s Electromagnetic Pulse
    11/6/2018

    The IoT Gold Rush—the move to integrate wireless transmission, circuitry and sensors into everyday household items and consumer goods to make them more appealing—is expected to increase the demand for EMC simulation. This article discusses the history of the move towards IoT technology and how simulation improves EMC in the IoT devices.

  2. Why is EMC Simulation Taking Off?
    11/6/2018

    This article discusses the importance of electromagnetic compatibility (EMC) in a variety of industries, including automotive, aerospace, defense, communications, railway, consumer electronics, energy, and healthcare. The challenge occurs when more and more electronic devices and circuits need to be fit into smaller areas while still maintaining EMC.

  3. Understanding Low Noise Spread-Spectrum Crystal Oscillators
    11/2/2018

    In the past, shielding and filtering were the most prevalent method used to control EMI. This method, however, can get very expensive and can be ineffective at times. The present trend is to control EMI at the source, using a single clock oscillator with spread-spectrum technology. This white paper discusses the theory of using low noise spread-spectrum crystal oscillator technology, and how it can be used to better control EMI in new technologies.

  4. Cobot, The Collaborative Robot – Get Ready For Industry 4.0
    10/30/2018

    Altair’s new cobot – a complex machine interacting with a human operator – is an example of a new successful design method with the use of simulation tools in industry 4.0. When creating complex products such as this, engineers must consider the entire mechatronics system, including structure, sensors, actuators with dynamic controls, electromagnetic compatibility. They must also interconnect machines for more flexibility, and increase productivity optimizing the maintenance process. This article discusses the design process for a cobot virtual demonstrator and how Altair’s HyperWorks was used in the process.

  5. Spectral Efficiency And Filter Temperature Stability
    10/26/2018

    This article discusses the use of he Shannon-Hartley Theorem in the context of 5G mmWave applications and how it may be used to find the number of bits/second expected in each section of bandwidth. This, in turn, relates to spectral efficiency and filter temperature stability.

  6. The GreenGT H2: First Prototype Electric/Hydrogen Competition Car Uses Fischer Connectors' Products
    10/26/2018

    In this case study, GreenGT, an independent company that designs, develops and markets clean and sustainable vehicle propulsion systems with a focus on competition and innovation, explains why their team has chosen to partner with Fischer Connectors to build the first prototype electric/hydrogen competition car.

  7. Eutectic Die-Attach Method Of GaN And GaAs MMICs
    10/25/2018

    This white paper reviews the many challenges to overcome when developing a repeatable eutectic die-attach process, including avoiding contamination, ensuring the quality of the pickup collets, and balancing efficiency and accuracy during screening procedures.

    10/22/2018

    Integra Technologies makes their GaN-on-SiC HEMT evaluation kits available for loan to their customers. This application note discusses how to properly handle and adjust these kits for optimal use in each application.

  9. Model-Based GaN PA Design Basics: The What And Why Of Intrinsic I-V Waveforms (Part 3)
    10/18/2018

    Understanding the impact and nuances of I-V curves is a fundamental part of learning how to design GaN power amplifiers. This is the third part in an ongoing series looking at the importance of GaN HEMT nonlinear models for rapid power amplifier (PA) design success.

  10. Understanding Microstrip Filter Topologies
    10/11/2018

    The behavior of transmission lines in RF systems becomes important when the transmitted frequency’s wavelength is short enough that the length of cable becomes a significant part of a wavelength. Microstrip consists of a conducting strip separated from a ground plane by a dielectric substrate.
