Faraday Rotation: What is it? Most microwave engineers have not studied ferrite components even if they have taken microwave engineering graduate classes. If you did take a microwave engineering course, the chapter about ferrimagnetic components was most likely near the end of the book, and you probably were glad of it! After all, every component up to that point was reciprocal – acting the [...]

Low Insertion Loss, High Power Handling, and Test Data: Why They Matter Millimeter-wave (MMW) systems often employ isolators to suppress standing waves and achieve optimal performance. Commercial isolators provide good isolation, typically more than 20 dB across full waveguide bands at lower frequencies (under about 85 GHz), and they also tend to have low port reflections. However, at MMW frequencies there is a great divide [...]
