RF tutorials - Diode balanced signal mixers

In this video I look at signal mixers implemented with diodes. First I look at what a mixer is supposed to do, and then I look at various constructive options, where complexity increases but also performance. Finally I try building the double balanced ring diode mixer and then perform some measurements to see just how it works.
