If you ever get the chance to meet me and bring up matrix decomposition as a topic of discussion, it would be an understatement to say I love matrix decompositions, and the most beautiful one is ei...

If you ever find yourself using a simple vector network analyzer (VNA) that can only take $S_{11}$ and $S_{21}$ measurements, this explanation might be an eye-opener on how to calibrate such a syst...

TRL calibration is one of the most powerful tools for VNA calibration, especially for planar circuit measurements where in-situ probing is often not possible. However, as I discussed in my previous...

Switch terms are a concept that is often misunderstood in vector network analyzers (VNAs). Although they are essential for VNA calibration, VNA vendors rarely discuss them in their user manuals. Un...

When using a vector network analyzer (VNA) to measure a device under test (DUT), calibration is a critical step. While there are many calibration methods out there, I believe the thru-reflect-line ...
