Rf Radio Radiofrequency Ham Tank Tankcircuit EE - Blog Posts

Zero to hero. My task was to create a sinusoidal generator via a Deadbug (the ugly metal plate with circuit elements soldered onto it) and a Printed Circuit Board (PCB). In theory, my sinusoid generator works but applying an electric current to a tank circuit. A tank circuit can be configured in many ways but I used a self-wound inductor and a capacitor in parallel, this works because the current induces an electric field in the capacitor and the E field induces a magnetic field in the inductor and they go back and forth creating oscillations. My tank is connected to a transistor (JEFT) that amplifies the oscillating signal.
