The architecture of a transmitter varies greatly depending on the application, particularly as it is single frequency, as in broadcasting, as multifrequency radio, broadband as military communications, amateur radio, and depending on the modulation type.
The simplest single-frequency transmitter in amplitude modulation includes: a source at the carrier frequency, usually following a quartz oscillator; a power amplifier amplitude modulated by the amplified signal; an antenna coupled to the output of the amplifier.
In broadcasting, the stages of low level, or "signal stages" comprising oscillator, modulator, filter, or generate the modulated carrier signal to a power of a few watts.
They are called excited. The power amplifier following is sometimes simply called "issuer".
Radiotelephone HF, VHF or UHF band, the need for selection of channel or frequency can lead to a frequency changing architecture similar to that of a receptor, for modulating and filter at a fixed frequency.
Radar power, the simplest scheme is a type of self-magnetron oscillator replaced by amplifiers for radar signal processing.
