A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite stable and the output power is around 200 mW.

One of the easiest, simplest ways to make an FM transmitter is to buy this kit from BuildCircuit. It’s amateur friendly, so anyone should be able to use it. What you need for assembling this ...

Here is a simple USB FM transmitter that could be used to play audio files from an MP3 player or computer on a standard VHF FM radio by connecting it to an USB port. The circuit use no coils that have ...

Scientists have taken advantage of graphene's special properties -- its mechanical strength and electrical conduction -- and created a nano-mechanical system that can create FM signals, in effect the ...

Placing a sheet of atom-thin graphene into a feedback circuit causes spontaneous self-oscillation that can be tuned to create frequency-modulated (FM) signals. Changyao Chen, Sunwoo Lee, Columbia ...
