#82: How to use a Diode as a Switch / Diodes as Switches / Basics of Diode Switches

This video answers a lot of questions about how diodes can be used to switch AC / RF signals. A lot of questions were asked about this after my last two videos which reviewed the schematics of a couple of QRP transceivers. These transceivers used a lot of diode switching. This video shows the basics of small signal switching with diodes, and also discusses large signal switching with PIN diodes.
