  1. How To Keep Noise Out Of RF Circuit Power Supplies
    12/19/2017

    RF circuits generating radio frequency signals are very sensitive to power supply noise, which can significantly degrade the performance of a system if not controlled. This article describes potential sources of noise and addresses different techniques for handling them.

  2. Common Applications For Radio Frequency (RF) Filters
    12/19/2017

    An RF filter permits a signal of interest to pass through while attenuating any undesired signals. This article describes the different filter shapes, or responses, when plotted in the frequency domain, defines general terms in filter utilization, and covers common types of applications that use RF filters.

  7. How To Quickly Evaluate High-Performance Oscillators Using Holzworth HA7402C Phase Noise Analyzer
    12/4/2017

    The process of evaluating the performance of ultra-low-phase noise oscillators requires phase noise test systems with lower measurement times, lower noise floor capabilities, and high reliability and repeatability of test data.

  8. Pulse Descriptor Word (PDW) Streaming With The R&S®SMW200A
    11/30/2017

    Radar warning receivers (RWR) and electronic support measures (ESM) require signal validation against realistic and agile radar scenarios. In the past, these complex scenarios have only been available with dedicated and highly integrated radar scenario simulators. Now, the R&S®SMW200A vector signal generator has been designed with the capabilities to take on the role. The instrument can generate the most modern I/Q modulated radar signals from streamed pulse descriptor words (PDW) received via LAN.
