Among the critically important conditions for optimal mobile device power source efficiency, ensuring reliable and long-term operation, is the matching of the output impedance of the radio transmitter with that of the antenna used. A step forward in the development of technology for the implementation of high-quality radio frequency radiation with minimal energy losses in telecommunications equipment could be devices that automatically match the output impedance of radio transmitters designed for high frequencies such as VHF and UHF. What has been achieved to date and implemented in the serial production of telecommunications equipment and in the majority of explorations is relatively optimized impedance matching between the output of the final amplifier stage and the transmitting antenna for a relatively wider frequency bandwidth. This leads to a significant deterioration in the transmission efficiency of some frequencies of the digital signal spectrum and a decrease in the data transfer rate. This publication presents the development and simulation of suitable elements for the implementation of automated impedance matching circuits.
