A transmitter is an electronic device used in telecommunications to produce radio waves to transmit or send data with the aid of an antenna. The transmitter can generate an alternating radio frequency flow that is applied to the antenna afterward, which, in turn, radiates this as radio waves. There are many types of transmitters, depending on the standard and the type of device. For example, many modern devices with communication capabilities have transmitters, such as Wi-Fi, Bluetooth, NFC, and cellular.
