  1. 5 Things To Consider When Designing Fixed Wireless Access (FWA) Systems

    In the earliest stages of 5G, fixed wireless access (FWA) systems will be used to deliver gigabit internet speeds to homes, apartments, and businesses in a fraction of the time and cost of traditional cable/fiber installations. Like other technological advancements, FWA has its own design challenges and considerations. This article presents five considerations to keep in mind when designing FWA systems.

  2. How To Choose The Best RF Filter For Your Application

    There are numerous options available for RF filters used in communications systems, test and measurement setups, and RF module designs. This article presents a number of key parameters to help you choose the best RF filter for each specific application.

  3. Introduction To Narrowband Internet Of Things

    The Narrowband Internet of Things (NB-IoT) is a new radio interface that is a part of Release 13, 3GPP. It is adapted to work in difficult radio conditions, especially in machine type traffic applications. Although NB-IoT is an independent radio interference, it is closely related to LTE networks. This white paper will introduce NB-IoT technology with an emphasis on the tight connection to LTE.

  4. Moving Toward Fully Connected Vehicles: Edge Computing For Advanced Automotive Communications

    Connected and Autonomous Driving (AD) vehicles bring new requirements for network architectures and the Cloud in order to support the new workloads and satisfy real-time service requirements. This white paper demonstrates how Edge Computing provides computing, storage, and networking capabilities in a network, and how this technology supports multiple services for connected AD vehicles.

  5. Case Study: Using FEKO® To Reduce Heating During MRI For Deep Brain Stimulation

    Research at the Department of Medical Biophysics at the Sunnybrook Research Institute (SRI) aims to develop and demonstrate the application of new technologies for brain imaging. A recent project focused on developing ways to try and safely image patients with Deep Brain Stimulation (DBS), and reducing the heat created during an MRI as a result implant interaction with RF transmission fields. This case study details how FEKO® simulation software was used to create the electrical and magnetic fields required for imaging in an MRI environment.

  6. An Introduction To PIM

    The increased awareness around passive intermodulation (PIM) comes with the growing complexity of how spectrum is utilized. This white paper offers a brief introduction to PIM, and considerations for designing a system with PIM in mind.

  7. When Should A Design Use Custom MMICs

    There are many challenges associated with improving the Size, Weight, and Power (SWaP) of electronic devices, including the limitation of the physical size and assembly processes, and spectrum congestion forcing new systems to move to higher frequencies. This article addresses these issues by discussing when to use a custom MMIC in the design process.

  8. Datalink Range Improvement

    When developing a communication datalink range, it is important to consider the ability to provide sufficient signal strength out to the intended operational range of the platform. This article discusses the options available to improve the datalink range for different applications.

  9. The Importance Of Size, Weight and Power (SWaP) To Mission Dominance In Unmanned Aerial Systems

    Unmanned aerial systems (UAVs) are continually advancing in respect to both defense and domestic applications. The fast development pace has led to an expanding list of missions that increase the demand on systems in terms of power consumption, payload, and the ability to operate beyond line of sight safely and reliably. This article discusses the importance of Size, Weight and Power (SWaP) to missions with UAVs.

  10. Power Amplifier Thermal Protection: Power Back Off

    Power amplifiers generate enough heat to require a method of sinking the heat away from the device. Sometimes, the amplifying device generates heat faster than the heat sink system can pull away. This article presents the use of temperature-controlled circuitry to shut down the internal amplifier to allow the device to safely cool before turning back on.
