TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Design And Implementation Of A Miniature X-Band Edge-Coupled Microstrip Bandpass Filter

  Microwave bandpass filters are the fundamental component used in many RF/microwave applications to eliminate interference from signals operating at nearby frequencies. This application note presents a straightforward and largely nonmathematical method for designing an edge-coupled, bandpass filter for X-band operations with a combination of filter synthesis, closed-form edge-coupled transmission-line models, and EM analysis using the Microwave Office circuit simulator within Cadence AWR Design Environment software.

• Directivity And VSWR Measurements: Understanding Return Loss Measurements

  The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

• Basic Bulk Current Injection Testing

  Bulk current injection (BCI) testing is a conducted susceptibility procedure that uses an injection current probe. This paper provides an example of BCI testing, covering all steps, including gathering the required equipment, pre-calibration procedures, injection testing procedures, and safety precautions.

• Four Practical Applications Using An Electronic Load

  This article presents four tips on how to test with electronic loads and illustrate the flexibility and usefulness of a DC electronic load. 

• Understanding Component EMC Testing for ICs

  If you're producing integrated circuit (IC) products for electromagnetic environments, you must test and pass all the regulatory electromagnetic interference (EMI) and safety requirements. Electromagnetic compatibility (EMC) testing is performed to ensure these components can be used in the intended environment without failing, degrading, or causing other equipment to fail.
