What is the component that generates the carrier wave at the correct frequency called?

The component that generates the carrier wave at the correct frequency is called an oscillator. Oscillators are essential in various electronic systems, including avionics, as they create continuous waveforms, specifically sine waves, that serve as the carrier signal for modulation. This carrier wave can then be used to convey information, such as audio or data, by varying its amplitude, frequency, or phase.

In avionics systems, having a stable and accurate carrier frequency is critical for effective communication and navigation. The oscillator is designed to maintain this frequency under varying conditions, ensuring reliable operation in various environments.

Amplifiers, transmitters, and receivers each play different roles in the signal chain. An amplifier boosts the strength of the signal, a transmitter combines the modulated signal and the carrier for transmission, and a receiver processes incoming signals to extract the information. However, the initial generation of the carrier wave is solely the function of the oscillator.
