The charge equations of the varicap diode are solved and show a discontinuity at the junction, hence showing the presence of deterministic chaos. After introducing the varicap diode and the diffusion ...

The transceiver itself is an Indian-assembled PCB with an updated circuit using a 12 MHz IF, varicap tuning, and large surface-mount components for easy modification. Just as with the original ...

There was a time when all radio receivers contained at least one, but with the arrival of the varicap diode and frequency synthesizer, the traditional tuning capacitor is difficult to find.

A varicap TV tuner circuit, from US patent 3643168 filed in July 1969. The schematics of this type of tuner didn’t vary too much. We’ve found an example with varicap tuning from US Patent ...

Here are a number of alternative ways to avoid problems when driving Varactor Diodes. Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a ...

The component between R8 and C21 represents the oscillator wich generates radio signal. D1 is a varicap diode ( like a variable capacitor or trimmer) controlled by audio signal. C12, C13 and L1 ...
