  1. Ten Cues That It’s Time To Look Into A Channel Modeler

    A question Remcom is often asked is, “How is Wireless InSite® different from our planning tools?” While every tool is a little different, the most important differences between Wireless InSite and planning tools emerge when users need to simulate 5G mmWave and MIMO systems. This white paper presents ten cues that your organization may need a channel modeling tool like Wireless InSite to supplement your network planning efforts.

  2. Pioneering Real Wireless Power Delivery™ At Ossia Inc.: FEKO In The Simulation Process

    Ossia Inc. revolutionizes the mobility and connectivity of people and industries through the creation of ecosystems for delivering smart wireless power to the small devices. Their patented wireless power Cota® technology is delivered like WiFi, is inherently safe, and provides real wireless power through the air and over a distance. This case study discusses how the Cota technology works and FEKO has been a powerful enabling tool for technology development at Ossia.

  3. Power Supply Management Of GaN MMIC Power Amplifiers For Pulsed Radar

    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

    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

    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. Electro-Optical Measurements Using Anritsu VNAs

    This application note describes the techniques and hardware required to characterize these components with economies of scale and flexibility not present in current Lightwave Component Analyzer (LCA) designs.

  7. Electrical-To-Optical And Optical-To-Electrical (E/O And O/E) Converter Measurements

    As the need for high speed optical modulators and detectors increase, it is important to understand the frequency response characterization of electrical-to-optical (E/O) and optical-to-electrical (O/E) converters in terms of parameters such as bandwidth, flatness, phase linearity, and group delay. 

  8. Electronic Packaging: Using EMI Material-Based Solutions

    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.

  9. Microwave Power Dividers And Couplers Tutorial

    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.

  10. Considerations When Choosing An RF Power Amplifier

    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.
