  1. 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.

  2. 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.

  3. Integration Considerations: Software-Defined Antenna Technology
    10/29/2018

    Proper integration of a software-defined antenna is key to obtaining maximum benefit for both 4G and 5G communication systems where MIMO antenna systems are required.

  4. 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.

    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.

  6. 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. The paper also details the key factors in determining if a eutectic die-attach process is sophisticated enough to serve the mission-critical applications of today’s aerospace, military, Satcom, and telecommunications applications.

  7. Modular Test Approaches For SSR Signal Analysis In IFF Applications
    10/24/2018

    Radar signal analysis applications require highly specialized test equipment to model and test transmitted or received signals. Secondary surveillance radar is a type of radar that is often used for air traffic control (ATC) applications as well as identify friend or foe (IFF) military applications. For these applications custom RF test racks are assembled for the specialty testing performed on this equipment. This application note covers a variety of modular test approaches for SSR signal analysis in IFF applications.
