A Capacitively Coupled Pin Injection Method for Troubleshooting Immunity Issues

Although most modern RF amplifiers have a high voltage device rating against impedance mismatch, special care is needed to prevent impedance mismatch. To avoid impedance mismatch of the power amplifier, often an attenuator is also recommended to be connected between the output of the power amplifier and the flying probe.

Cable Antennas and Ferrite Cores

In this column, the author offers a brief summary of a more systematic approach for using ferrite cores on cables. This summary can serve as a “ferrite core checklist” for design and test engineers.

Troubleshooting EMC Problems Like an MD

This article describes three troubleshooting methodologies doctors use to diagnose (troubleshoot) medical problems. These same techniques have proven useful in my own EMC consulting practice.
