ABSTRACT:
A tuning circuit is provided for increasing the power transfer between first and second electrically coupled utilization circuits while controlling the effective source reflection coefficient thereby increasing the power available to the latter wherein the input signal provided at the output of the first utilization circuit is reflected back reducing the power available at the input of the second utilization circuit. The input signal is applied to the first input of the power combiner while a feedback signal proportional to the power loss between the first and second utilization circuits is applied to the second input of the power combiner. The output of the power combiner is increased by the feedback signal for compensating the power loss of the input signal such that the power available to the second utilization circuit is increased.
