A power amplifier system for amplifying RF signals includes an RF signal feedback arrangement to compensate for the loss of RF output power from isolation ports of hybrid couplers in the system and reduces heat dissipated at the terminations, e.g., a resistor, or other components of the isolation ports of the hybrid couples. The amplitude of the signals, which is not realized at either of the output ports of the power divider (one of the hybrid coupler) and/or either the output ports of the power combiner (one of the hybrid coupler) at the termination of the isolation ports of the hybrid couplers, is fed back into the power amplifier system.
