what is fm transmitter?we supply it in Guangzhou China
FM transmitter Simply speaking, the sound through the FM radio technology launched into the air, then the most common radio can listen to the sound of this emission machine. In general, the FM transmitter FM radio transmitter, referred to, mainly for voice and music programs of the FM radio station launched by wireless means. Any FM radio station, regardless of their size (the national radio station, the provincial radio station, the municipal radio station, county radio, township radio, village radio, campus radio station, enterprises and institutions stations, military barracks radio, etc.) will be audio broadcast control equipment, audio and transmission equipment, FM transmitter, and launch day feeder. Radio coverage, you need to launch the power FM transmitter, high-gain transmitting antenna mounted on a high from the ground; coverage of a small radio, you need to launch a small-power FM transmitter gain antenna and mounted on a suitable height. Typically, the FM transmitter power level of 1W, 5W, 10W, 30W, 50W, 100W, 300W, 500W, 1000W, 3KW, 5KW, 10KW. Can also be based on actual needs, customized special power FM transmitter. FM transmitter There are many classification: FM transmitter use situation minute, can be divided into professional-grade FM transmitter and amateur-level FM transmitter, professional-grade is mainly used in professional radio and sound quality, reliability requirements of the occasion, while the amateur level is mainly used for non-professional radio and the sound quality and reliability requirements of the general requirements of the occasion; Broadcast can be divided into a stereo radio and single-channel broadcast; Points, can be divided into analog FM transmitter and digital FM transmitter FM transmitter circuit schematic: With the rapid development of electronic technology, especially professional-grade FM transmitters, digital FM transmitter is gradually replacing analog FM transmitter , the difference between digital and analog is very simple, to see whether the use of software radio technology (DSP + DDS) design.
