Abstract
A method and system to balance a signal through a plurality of parallel amplifier elements of an amplifier device. An input signal to the amplifier device is divided substantially equally among a plurality of parallel amplifier elements. A signal through each of the amplifier elements is measured. If any of the measured signals deviates by a predetermined threshold from a reference signal, an adjustment to an input parameter to a tuning circuit associated with the particular amplifier element is determined. The determined adjustment is applied to the particular a tuning circuit to appropriately adjust the output of the deviating amplifier element. The output of the plurality of amplifier elements is combined as the total output of the amplifier device.
