  1. Choosing The Right Connector For Communications Networks

    Several important considerations must be made when choosing a connector for communications systems. This white paper will compare and contrast both classical and new connectors, and highlight their differences in terms of electrical and mechanical performance for specific applications.

  2. GaN HEMT Models 101: How Do Nonlinear Models Help With GaN PA Design? (Part 1)

    GaN power amplifier design requires some different approaches and thinking compared to LDMOS or GaAs. Learn how nonlinear simulation models, like those from Modelithics, can help speed up design processes by downloading Part 1 of a two-part introductory series.

  3. Advanced Spectrum Logging

    Troubleshooting an RF interface requires the use of a spectrum analyzer where the user must be watching the screen to witness the interference. This application note presents the Rack-Mount SignalHawk™ Spectrum Analyzer with Advanced Spectrum logging (ASL) as a solution to this problem.

  4. Calibration Techniques For Precision Power Measurement In Semiconductor Process Applications

    Radio frequency power measurement has been an important component of semiconductor processing since the time that plasma was first used for wafer processing. Power measurement was, and continues to be important, as radio frequency energy is used to excite the plasma, and the plasma characteristics are in large part determined by the excitation energy. In this article, we will discuss various means of measuring radio frequency power, along with their limitations. In addition, we will present the best calibration methods for radio frequency power measuring instruments.

  5. Managing Complex Land Mobile Radio Systems

    The management of any single site in a multiple-site, multiple-channel land mobile radio communications system can often be a complex task. When failures or degradation in performance are reported, it may be necessary to make multiple trips to fully diagnose or correct the issue. This can become a huge hassle, especially for remote sites with low accessibility. This application note presents the Bird Model 3141 Channel Power Monitor as a solution for addressing the complexity of land mobile radio system management.
