The high level transmitter .it consists of crystal oscillator buffer amplifier, driver amplifier, modulator amplifier, antenna matching network, modulator power amplifier, audio amplifier. The crystal oscillator generates carrier frequency. The buffer amplifier and driver amplifier amplify the power level of the carrier to require value. The amplified carrier is given to class c modulator amplifier. The modulating signal is audio signal given to the audio amplifier. It is further amplified by audio power amplifier at a level suitable for modulation. The class c modulator amplifier modulates the carrier input according to modulating audio signal. The output of the class c modulator amplifier is AM and it is given to antenna through some antenna matching network
