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.

AM radios are relatively simple devices, and building one is a good way to start exploring the world of radio communications. [GreatScott] does exactly this in the video after the break, building both ...

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 ...

For the first time, researchers have used a laser as a radio transmitter and receiver, paving the way for towards ultra-high-speed Wi-Fi and new types of hybrid electronic-photonic devices. You've ...

German manufacturers Plisch and RFmondial have produced a VHF Band III DRM transmitter, which the companies said is the first ...

Targeting OC-192, 10-Gb/s short reach data links, the VSC7166 optical interconnect IC integrates both transmitter and receiver circuits on a single chip. The very-short-reach device converts 16-bit, ...

A key component for these wireless battery power chargers is a power transmitter IC that offers robust, standalone applications capable of transmission distances up to 15mm and tolerance of poor coil ...
