  1. Role Call: Senior Field Application Engineer

    Role Call, a series on RF Globalnet, takes a “peek behind the curtain” to help answer the questions related to different jobs and career paths in the RF and microwave industry. Recently, Kenny Lee, Senior Field Application Engineer at LitePoint, took time to answer some questions about his occupation.

  2. 5G Over-The-Air Performance Measurement And Evaluation Using FieldFox Handheld Analyzers

    Massive MIMO and beamforming are an integral part of 5G, and early extensive tests are required to make them deployable. Keysight’s FieldFox analyzer provides propagation loss test, antenna pattern over-the-air test, phased array antenna verification and many other common mm-Wave tests in a single instrument.

  3. Automatic And Fail-Safe Biasing Of GaN Transistors

    GaN HEMT transistors require a negative voltage for the gate and a positive voltage for the drain. Since they are depletion mode devices, it is critical to supply a negative voltage to the gate before any positive voltage is applied to the drain, otherwise the transistor will draw its maximum possible drain current from the supply which is likely to lead to excessive thermal dissipation and the device burning out. For these reasons Integra Technologies has developed a fully automatic and fail-safe bias circuit for its GaN transistors that only requires a single positive voltage power supply.

  4. 5 Simple Steps For Truly Effective Design Reviews

    As electronics and RF systems have become increasingly complex, the need to catch and fix errors during the design phase of a project has become increasingly important. Catching an error during the design phase is orders of magnitude less expensive to fix than catching it during the manufacturing or test phases. This article offers five simple steps for ensuring the most productive design review possible in each project.

  5. Digitizer Applications Using High-Performance Signal Analyzer

    This application note explains how to cut development and manufacturing time and costs by combining the signal analyzer MS2850A with a dedicated data-transfer interface for high-speed transfer of large amounts of digitized data captured over long time periods. The paper also explains the operation of the MS2850A as a single port digitizer for RF/microwave signals.

  6. Benefits Of Time-Domain Electromagnetic Simulation For Automotive Radar

    The requirements for automotive radar sensors in common ranges - such as 24 GHz and 77 GHz - are becoming more stringent and engineers need to understand how design decisions affect performance.  

  7. Taking the IoT’s Electromagnetic Pulse

    The IoT Gold Rush—the move to integrate wireless transmission, circuitry and sensors into everyday household items and consumer goods to make them more appealing—is expected to increase the demand for EMC simulation. This article discusses the history of the move towards IoT technology and how simulation improves EMC in the IoT devices.

  8. Why is EMC Simulation Taking Off?

    This article discusses the importance of electromagnetic compatibility (EMC) in a variety of industries, including automotive, aerospace, defense, communications, railway, consumer electronics, energy, and healthcare. The challenge occurs when more and more electronic devices and circuits need to be fit into smaller areas while still maintaining EMC.

  9. Advanced Radar Analysis Tools For Measuring Modern Radars

    Designing modern electronic warfare and radar systems presents many challenges, including developing solutions with the flexibility and adaptability required for next-generation threat detection and avoidance. In this application note, Tektronix discusses how their broad portfolio of test equipment reduces testing uncertainty in the design process and delivers confidence in the integrity of increasingly complex radar designs.

  10. Understanding Low Noise Spread-Spectrum Crystal Oscillators

    In the past, shielding and filtering were the most prevalent method used to control EMI. This method, however, can get very expensive and can be ineffective at times. The present trend is to control EMI at the source, using a single clock oscillator with spread-spectrum technology. This white paper discusses the theory of using low noise spread-spectrum crystal oscillator technology, and how it can be used to better control EMI in new technologies.
