In contrastm the transmitter schematic we present here eliminates some of those problems, using varactor diode for tuning and modulation, givind great sensitivity without an audio amplifier. FM ...

This simple FM transmitter links your home-entertainment ... IC1 is a voltage-controlled oscillator with integrated varactor diode. Its nominal frequency of oscillation is set by inductor L1.

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...

The varactor diode market is projected to register a CAGR of almost 11% by 2023. The advertising industry is increasingly using FM broadcast stations to advertise their products and offerings.
