  1. 5 Simple Steps For Truly Effective Design Reviews

    As electronics and RF systems have become increasingly complex, the need to catch and fix errors during the design phase of a project has become increasingly important. Catching an error during the design phase is orders of magnitude less expensive to fix than catching it during the manufacturing or test phases. This article offers five simple steps for ensuring the most productive design review possible in each project.

  2. Benefits Of Time-Domain Electromagnetic Simulation For Automotive Radar

    The requirements for automotive radar sensors in common ranges - such as 24 GHz and 77 GHz - are becoming more stringent and engineers need to understand how design decisions affect performance.  

  3. Taking the IoT’s Electromagnetic Pulse

    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.

  4. Why is EMC Simulation Taking Off?

    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.

  5. Understanding Low Noise Spread-Spectrum Crystal Oscillators

    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.

  6. Cobot, The Collaborative Robot – Get Ready For Industry 4.0

    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.

  7. Spectral Efficiency And Filter Temperature Stability

    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.

  8. The GreenGT H2: First Prototype Electric/Hydrogen Competition Car Uses Fischer Connectors' Products

    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.

  9. Eutectic Die-Attach Method Of GaN And GaAs MMICs

    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.
