It was summer 2019 when I first got introduced to wirebonding. It is not like I did not know what the term meant, but that was the first time I got to actually operate a bonder machine, and I manag...

Ok, no one can disagree that beamforming is not cool. But you know what’s cooler? Knowing how it works. This post is based on a lab manual I wrote years ago for a university course on MIMO (Multipl...

Nostalgia can be bittersweet, as it reminds you that time moves forward. While digging through my undergraduate documents, I was reminded of my old Bachelor project on Multilateration/Trilateration...

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 ...
