The problem of improving the efficiency of radio transmitters having independent power supply and forming signals with large peak factor is considered. The aim of the work is to develop radio transmitter for mobile object or unmanned vehicle using automatic amplitude control system, allowing to achieve increasing efficiency of the transmitter without simultaneous deterioration in the quality of generated radio signal. A block diagram of 2.4 GHz band radio transmitter with autonomous power supply, providing an increased value of efficiency has been designed. The simulation and experimental verification of its stages has been performed.
Key words: unmanned vehicles, peak factor of radio signal, efficiency coefficient of radio transmitter, automatic amplitude control system, energy efficiency of transmitter.
