Abstract
A method and apparatus for the automatic matching of a transmitter to an antenna is disclosed. A voltage signal proportional to the square root of the load impedance of the final stage of the transmitter is compared to a signal which is proportional to the square root of the nominal value of the final stage load impedance and the difference is used as the criteria for tuning a load coupling coil connecting the final stage of the transmitter to the antenna.
