Best of Do-it-yourself FM Transmitters 1W FM Transmitter with 4 transistors This FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a ...

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 ...

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 ...

World's smallest FM radio transmitter Date: November 18, 2013 Source: Columbia University School of Engineering and Applied Science Summary: Scientists have taken advantage of graphene's special ...

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

Engineers have created the smallest FM radio transmitter using graphene, the strongest and thinnest material in the world.
