Abstract :
The results of an investigation into the effect of numerous ferrite core materials and sizes on the performance of push-pull RF amplifier circuitry is presented. Power gain, return losses, power gain stability with temperature, power output capability and core temperature under RF overload conditions are examined as a function of various core characteristics.
