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 ...

How are we going to transmit our signal? Feeling ambitious, we decided to go wireless. We may not to able to make a mobile phone system but our very own radio station with a transmitter and receiver ...

NBFM or Narrow Band Frequncy Modulation is used in this 27 MHz transmitter circuit schematic. This circuit is an application by Motorola MC2833 – VHF transmitter with FM modulation and narrow band in ...

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 ...

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, ...
