  1. 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.

  2. 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. 

  3. 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.

  4. 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. This article discusses the importance of Size, Weight and Power (SWaP) to missions with UAVs.

  5. 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.

  6. How To Speak Radar: Basic Fundamentals And Applications

    The evolution of radar has grown steadily over the decades to its present level that employs sophisticated computerized techniques which has stimulated the development of increasingly complex components. This white paper provides a basic introduction to radar technologies and to the application of radar equipment.

  7. Industrial IoT: How Smart Alerts And Sensors Add Value To Electric Motors

    This article explores how industrial IoT can produce real value for electric motors and factories.

  8. Understanding Power Divider/Combiner Types And Functionality

    Both resistive type and reactive type power divider/combiners can be used to fan-in or fan-out RF signals. However, both types distribute RF signals in a different fashion. This white paper offers guidelines and considerations for determining a divider/combiner for each application.

  9. 10 Hints For Making Successful Noise Figure Measurements

    Noise figure often characterizes a receiver and how well it can detect weak signals in the presence of self-generated noise. The process of reducing noise figure begins with a solid understanding of the uncertainties in your components, subsystems, and test setups. 

  10. Design Of A Cost-Effective, Hybrid Input-Matched GaN Transistor For S-Band Radar Applications

    This article describes design of a GaN transistor with internal GaAs input matching. The input matching network is designed for the 2.7 – 3.5 GHz frequency range, making the transistor suitable for S-band radar applications.
