What is the function of dehydrator in an FM transmitter?

An FM transmitter typically does not have a dehydrator as part of its circuitry. Instead, a power amplifier (PA) stage usually comes after the modulation process to amplify the signal before being radiated by the transmitting antenna.

A dehydrator, meanwhile, is commonly found in food processing or chemical industries for its ability to effectively remove moisture from certain materials through heat drying and cooling processes.
