  3. Power Supply Management Of GaN MMIC Power Amplifiers For Pulsed Radar
    2/16/2018

    Today’s management systems must be extremely flexible, reusable, and easily adaptable to various RF amplifier architectures. Their enclosed RF amplifier MMICs are expensive and, as a result, the performance and temperatures of these systems must be monitored in real-time. 

  4. Conducted And Over The Air Antenna Array Testing – The Way To 5G
    2/15/2018

    5G networks need to be designed to offer more capacity and flexibility while lowering overall systems operation expenses. This paper discusses various test solutions that can address current and future requirements for antenna verification, including conducted and over-the-air test methods.

  5. Wideband Optical Modulator And Detector Characterization: Uncertainties And The Impact On Eye Diagrams/Time Domain Modeling
    2/13/2018

    Optical modulators and detectors have been characterized and calibrated over the years, but less attention has been made to the optimization of converter measurement uncertainties in a practical user context. Since frequency dependencies of various error mechanisms are different, the wide bandwidths could require procedural changes for optimum results. From a subsystem simulation/modeling/analysis perspective, accuracy in microwave/mm-wave frequency domain characterizations is important but sometimes not studied in terms of how they affect final eye diagram, bit error rate, or other higher level system operational parameters. This paper explores these characterization and calibration processes, as well as the net uncertainties, and their impact on example eye diagram generation.

  6. Electronic Packaging: Using EMI Material-Based Solutions
    2/12/2018

    When designing new printed circuit boards for new electronic devices, it is important to consider electromagnetic interference (EMI) shielding solutions early. One of the main issues encountered is when the individual components could pass EMI testing, but as the components are combined into subsystems or into the final product, the device under test (DUT) fails. Incorporating EMI shielding materials as part of an initial design is the most cost-effective way to prevent these last-minute issues during testing.

  7. Microwave Power Dividers And Couplers Tutorial
    2/12/2018

    Power dividers and couplers are straightforward passive components. In order to design a component with high performance, designers must give attention to design detail, execution of the design, and quality of the fabrication. This article provides a basic tutorial of power dividers and couplers, and defines power divider and coupler terminology.

  8. Considerations When Choosing An RF Power Amplifier
    2/12/2018

    This white paper talks about the important operating parameters to consider when choosing an amplifier, as well as the various types of amplifiers offered by Corry Micronics.

  9. Introduction To SAW Filter Theory And Design Techniques
    2/7/2018

    Tradeoffs must be considered when selecting the best filter for system design applications. SAW filter technology offers reduced size and weight, which results in lower overall costs. This paper presents general SAW theory and performance information.

  10. Paving The Way To Self-Driving Cars With Advanced Driver Assistance Systems
    2/7/2018

    The excitement about the future of self-driving cars can make it easy to overlook numerous short-term developments by automotive manufacturers. Collectively known as Advanced Driver Assistance Systems (ADAS), these developments must be able to make cars safer, and their gradual introduction must also improve road safety. In addition, ADAS features represent an evolution in vehicle sensing, intelligence, and control that will ultimately lead to self-driving cars. This white paper discusses the challenges in ADAS adoption, and the importance of using the most advanced technologies for its future.
