The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...

A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant ...

The following is excerpted from Chapter 8 from “RF Circuit Design, 2e” by Christopher Bowick. The fundamental operation of an RF front end is fairly straightforward: it detects and processes radio ...
