![]() ![]() The term transmitter is often abbreviated "XMTR" or "TX" in technical documents. A transmitter and a receiver combined in one unit is called a transceiver. This usage typically includes both the transmitter proper, the antenna, and often the building it is housed in.ĭescription A radio transmitter is usually part of a radio communication system which uses electromagnetic waves ( radio waves) to transport information (in this case sound) over a distance.Ī transmitter can be a separate piece of electronic equipment, or an electrical circuit within another electronic device. The term is popularly used more specifically to refer to a broadcast transmitter, a transmitter used in broadcasting, as in FM radio transmitter or television transmitter. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitters, even though they often have similar circuits. The term transmitter is usually limited to equipment that generates radio waves for communication purposes or radiolocation, such as radar and navigational transmitters. #Radio transistor 1952 Bluetooth#Transmitters are necessary component parts of all electronic devices that communicate by radio, such as radio and television broadcasting stations, cell phones, walkie-talkies, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. When excited by this alternating current, the antenna radiates radio waves. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. It broadcasts at 101.9 MHz with a radiated power of 48 kW.
