| Radio Design 101 - Episode 3 - RF Amplifiers A relatively complete discussion of amplifier circuits, including the electronic devices used (tubes/valves, transistors (JFET, BJT, MOSFETs)), how they're biased, and how the AC behavior is analyzed and understood in terms of gain and input/output impedances. In keeping with the previous videos in this series, the focus is on RF amps, but much of the theory applies to audio amplifiers as well. A few full circuit schematics are used to show real-world examples. https://youtu.be/UUlqW-vSq9M |
