Radio transmitters convert information signals into RF signals over long distances. It is categorized into different types based on the type of modulations used, based on the power, and frequency, and based on services used. The amplitude modulation, frequency modulation, and phase modulation of radio transmitters are categorized according to the type of modulation used, the radio broadcast, radiotelephone, radiotelegraph, television, radar, and navigation radio transmitters are categorized based on the services involved. The long wave radio transmitters are used in aeronautical and marine navigation and the range is 30-300 kHz, the very high-frequency radio transmitters are used in FM broadcasting in the 88-108 MHz range. The long wave, short wave, and medium wave radio transmitters are categorized based on the frequency range used. The short-wave radio transmitters are used in used for long-distance communication by virtue of ionospheric reflection and their range is from 3-30 MHz. The transmitters play an important role in all electronic devices which uses radio to communicate, such as walkie-talkie, cell phones, television broadcasting station, etc. 1).
