  1. Empowering Innovation In Startups At Altair Nasdaq Entrepreneurial Event

    The Startup ecosystem, made up of entrepreneurs, universities, investors, and researchers, is a community filled with innovative, thought provoking individuals driven by the desire to produce products and devices to provide a sustainable way of life. Last week Altair had the unique privilege of hosting an event at the Nasdaq Entrepreneurial Center in San Francisco, “Accelerate Your Startup to Market Leadership”, to introduce our technologies to this community through the lens of their peers. Special guest speakers provided their perspectives on the essence of a startup, their passion for innovation, and the importance of the virtual playground.

  2. How NB-IoT And LTE-M Fit Into The IoT Ecosystem: The Future Of Cellular IoT

    The future of the Internets of Things (IoT) will expand the use of cellular communications beyond smartphones and tablets to an extraordinary range of applications and connected devices. A significant number of these applications will require long-range connections. Two new standards, NB-IoT and LTE-M, have potential uses and some implementation options for device makers looking to add cellular connectivity.

  3. How To Efficiently Design Power Transformers

    This white paper discusses a few steady-state and transient tests that determine the electrical and mechanical constraints power transformers will have to endure in their life. In addition, thermal studies can complete these analyses to detect and prevent hot spots on the tank or in the windings.

  4. Introduction To The Vehicle-To-Everything Communications Service V2X Feature In 3GPP Release 14

    The future of cooperative intelligent transportation systems promises to provide increased efficiency and to additionally reduce road traffic fatalities and serious injuries. The 3GPP Long Term Evolution in release 14 introduces and specifies the vehicle-to-everything communications service. After a brief overview of the system, this paper introduces the V2X feature in release 14 in detail.

  5. When Choosing Test Equipment, Don’t Forget the Interface

    When purchasing RF test equipment, it is tempting to concentrate on specifications, such as insertion loss, frequency range, or VSWR, without think ahead on the fact that a complex testing scheme usually involves integrating multiple pieces of equipment from multiple manufacturers. For multiple devices to work seamlessly together in an automated test flow, designers and engineers must also consider the interface that would be used to drive the testing equipment. This article discusses the differences in proprietary and generic interfaces, the benefits each type has to offer, and offers some solutions to potential interface barriers and how to remove them.

  6. Implementing High Performance Filters In Millimeter Wave Applications

    One of the challenges that 5G engineers face is how to sufficiently implement high-performance RF filtering in millimeter-wave applications. This white paper looks at some of the considerations to make when selecting a filter technology for millimeter-wave applications.

  7. Filter Terminology And Specifications

    This guide acts as a quick reference for terms used to discuss filter technologies.

  8. Webinar: First-Time-Right Design Of Matching Circuits For Complex Antenna And RF Applications

    Antenna and RF design often need matching circuits to widen the operation bandwidth and to increase the performance of wireless systems. In the design of these matching circuits, many factors can cause the performance of the manufactured matching circuit to differ from the simulated performance. This webinar identifies the sources of discrepancy between measurements and simulation and demonstrates a first-time-right design flow of matching circuit using the FEKO electromagnetic solver and the Optenni Lab RF Design Automation Platform.

  9. Multi-Physics Design And Optimization Of A Complex Radar System

    Today’s products are a combination of advanced technologies that mix electrical parts with controllers and embedded software. A model-based development approach is used to efficiently manage products through concept studies, control design, multi-domain system simulation and optimization.

  10. RF Filtering For 5G Millimeter Wave Applications

    This white paper discusses mmWave 5G communications. The paper also offers a guide for available RF filtering options at these frequencies, review mmWave frequencies and their applications, and cover what filtering technologies will be available for use at mmWave frequencies.
