Raadiosaatjates refers to radio transmitters in Estonian. A radio transmitter is an electronic device that produces a radio frequency alternating current, with the purpose of being converted into electromotive force of an antenna. This antenna then radiates the alternating current out from the antenna as radio waves. Radio transmitters are also called signal generators, because they are used to generate radio signals. Radio transmitters can be broadly categorized by their intended use and output power. They are essential components in a vast array of communication systems, enabling the transmission of information wirelessly over distances.

The fundamental principle behind a radio transmitter is the generation of an oscillating electrical signal at a specific radio frequency. This signal is then amplified and modulated to carry information, such as audio or data. Modulation involves altering some characteristic of the radio wave, like its amplitude or frequency, in accordance with the information being transmitted. The modulated signal is then fed to an antenna, which converts the electrical energy into electromagnetic waves that propagate through space. The efficiency and range of a transmitter depend on factors like its power output, the frequency it operates on, and the design of its antenna. Applications range from broadcasting radio and television signals to mobile phone communication, radar systems, and satellite transmissions. The development of radio transmitters has been a cornerstone of modern telecommunications and continues to evolve with advancements in technology.
