- Power supply — The energy source used to power the device and create the energy for broadcasting
- Electronic oscillator — Generates a wave called the carrier wave where data is imposed and carried through the air
- Modulator — Ads the actual data into the carrier wave by varying some aspect of the carrier wave
- RF amplifier — Increases the power of the signal in order to increase the range where the waves can reach
A transmitter is an electronic device used in telecommunications to produce radio waves in order to transmit or send data with the aid of an antenna. The transmitter is able to generate a radio frequency alternating current that is then applied to the antenna, which, in turn, radiates this as radio waves. There are many types of transmitters depending on the standard being used and the type of device; for example, many modern devices that have communication capabilities have transmitters such as Wi-Fi, Bluetooth, NFC and cellular.
