Logarithmic Amplifier/Detector Characterization Utilizing A Modern Vector Network Analyzer

2014-12-21 18:41:43| rfglobalnet Home Page

When characterizing the log amp/detector, a number of RF measurements must be performed. At minimum, those tests include input (S11) match, output (S22) match, and output log conformance. Log detector errors include DC output bias and slope error. Limited outputs must also be measured for absolute power and input threshold. While these tests many appear straightforward, the conventional test systems typically used to perform them often face a number of limitations. Fortunately, many of these limitations can now be overcome with just a single instrument—a modern vector network analyzer (VNA).
