  2. Selecting Microstrip Filters To Deliver Small Size At High Frequencies

    When selecting a filter implementation, one common factor across all frequencies is optimizing the size of the filter to the application and its required performance. This article discusses the benefits of microstrip filters to deliver higher frequencies in mmWave applications at smaller component sizes.

  3. Specifying RF/Microwave Power Amplifiers For EMC Testing

    Historically, amplifier selection for electromagnetic compatibility (EMC) testing was based mainly on meager knowledge and information scattered across the EMC industry. However, proper EMC amplifier selection is an important step in achieving required RF levels. This application note offers the information necessary to make the optimal amplifier selection by taking the reader through numerous considerations.
