This is a short range transmitter with a transmission range of about 10-20 meters. Follow these steps and the FM transmitter circuit diagram, to make a super easy FM transmitter.

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.

The FM transmitter circuit itself is based off one of [Art Swan]’s builds, but instead of the solderless breadboard construction you would expect to find in a small demo circuit, [Angelo] went ...

Rejecter circuits are used to isolate the transmitters from each other and prevent excessive cross-modulation and intermodulation occurring in their output stages.

A team of engineers from Columbia University has created a nano-mechanical system with the ability to create FM radio signals. In other words, they've built what is effectively the world’s ...
